Imaging Diagnosis of Perianal Leiomyoma: A Case Report.

ABSTRACT: A leiomyoma is a benign mesenchymal neoplasm that usually develops where smooth muscle is present. In this report, we present the case of a 75-year-old woman who sought medical attention due to pelvic organ prolapse and urinary incontinence, and without defecatory symptoms. Both pelvic floor ultrasound and magnetic resonance imaging (MRI) examination showed a well-defined mass in the ischioanal fossa, eventually diagnosed as a perianal leiomyoma. It is considered a rare entity because of its location involving the anal sphincter and clinical features. We describe the ultrasonographic and MRI findings of this perianal leiomyoma, together with differential diagnoses and immunohistochemical characterization.

Pulmonary benign metastasizing leiomyoma: A case report.

Project description:Uterine leiomyoma is the most common benign gynecological tumor. Rarely, it has benign extra-uterine growth patterns, including benign metastasizing leiomyoma (BML), with lungs being the most common metastatic site. We present a case of a 47-year-old female who, 3 years prior to presentation, underwent abdominal supra-cervical hysterectomy for benign leiomyoma. Approximately 6 months prior to presentation, she was seen for shortness of breath and chest pain. A CT of the chest revealed multiple new non-calcified pulmonary nodules bilaterally. PET/CT demonstrated mild FDG uptake in multiple lung nodules, with no significant extra-thoracic sites of abnormal FDG uptake. A CT guided lung biopsy showed a low grade, smooth muscle tumor. Immunohistochemical staining was positive for smooth-muscle actin and desmin, estrogen and progesterone receptor and was negative for CD117, HMB-45, CD34, pan cytokeratin and EMA. She underwent wedge resection of one of the nodules which confirmed the above findings. A cytogenetic analysis was also performed, which was consistent with pulmonary BML. She ultimately underwent left lower lobe resection and was started on a daily aromatase inhibitor. BML is a rare disease usually seen in women of reproductive age. The pathogenesis and treatment remain controversial. BML mostly tends to have an indolent course and a favorable outcome.

Perianal Paget's Disease-a Case Report and a Review of Current Diagnosis and Management.

Project description:Paget's disease is an intraepithelial adenocarcinoma arising from the apocrine gland component of the skin. Paget's disease is most common in the breast but extra mammary disease is also seen. Perianal Paget's disease is a rare form of extramammary disease with few cases reported in literature. It can be primary-arising from the skin or secondary-cutaneous metastases of anorectal or genitourinary malignancy. We hereby wish to report a case of perianal Paget's disease that presented as an eczematous lesion and was diagnosed incidentally on biopsy. After appropriate staging, the patient underwent wide local excision till negative margins were obtained. The resultant tissue defect was successfully covered by split-thickness skin grafting.

Magnetic resonance imaging (MRI) of perianal granular cell tumor: A case report and literature review.

Project description:Granular cell tumor (GCT) is a rare soft tissue neoplasm. At present, there is limited information available on the incidence, diagnosis, and treatment of GCTs. Therefore, we perform magnetic resonance imaging (MRI) of a perianal GCT case and review the literature of other reported cases to obtain a more comprehensive understanding of the disease. Here, we describe a rare case of perianal GCT in a 53-year-old female who presented with recurrent abdominal pain. Contrast-enhanced MRI demonstrated a well-defined perianal GCT mass, and the diagnosis was confirmed by immunostaining after mass excision. During a 10-month follow-up, there had been no evidence of recurrence. In addition, we discussed the findings of other perianal GCT cases, with regard to their age, gender, MRI analysis results, pathologic features, and treatment outcomes.

Case Report: Molecular Profiling Facilitates the Diagnosis of a Challenging Case of Lung Cancer with Choriocarcinoma Features

Project description:Accurate diagnoses are crucial in determining the most effective treatment across different cancers. In challenging cases, morphology-based traditional pathology methods have important limitations, while molecular profiling can provide valuable information to guide clinical decisions. We present a 35-year female with lung cancer with choriocarcinoma features. Her disease involved the right lower lung, brain, and thoracic lymph nodes. The pathology from brain metastasis was reported as “metastatic choriocarcinoma” (a germ cell tumor) by local pathologists. She initiated carboplatin and etoposide, a regimen for choriocarcinoma. Subsequently, her case was assessed by pathologists from an academic cancer center, who gave the diagnosis of “adenocarcinoma with aberrant expression of β-hCG” and finally pathologists at our hospital, who gave the diagnosis of “poorly differentiated carcinoma with choriocarcinoma features”. Genomic profiling detected a KRAS G13R mutation and transcriptomics profiling was suggestive of lung origin. The patient was treated with carboplatin/paclitaxel/ipilimumab/nivolumab followed by consolidation radiation therapy. She had no evidence of progression to date, 13 months after the initial presentation. The molecular profiling could facilitate diagnosing of challenging cancer cases. In addition, chemoimmunotherapy and local consolidation radiation therapy may provide promising therapeutic options for patients with lung cancer exhibiting choriocarcinoma features.

Primary leiomyoma in the hepatorenal space: a case report.

Project description:Leiomyomas can occur in various organs and tissues throughout the body, but reports of their occurrence in the hepatorenal space are rare. The video presents a comprehensive breakdown of the diagnostic procedures and surgical resection procedures. Emphasizing the key strategies for easy misdiagnosis. For leiomyomas occurring in rare sites, the compression on surrounding organs often leads to blurred boundaries in imaging, making it difficult to determine their origin and resulting in misdiagnosis. For rare tumors located at the junction areas, in order to achieve better treatment outcomes, abdominal exploration and intraoperative multidisciplinary consultations should be carried out under sufficient preoperative preparations.

Perianal basosquamous carcinoma treated with radiation therapy, a case report

Project description:Background Perianal basal cell carcinoma (BCC) is very rare and estimated to account for 0.08% of all BCC and 0.02% of all anorectal neoplasms. Perianal lesions are more likely to be squamous cell carcinoma (SCC) as BCC usually develops on areas of skin exposed to ultraviolet (UV) light such as the face and arms. Proper diagnosis with the assistance of immunohistochemistry (IHC) stains to distinguish the two entities can help inform the suitable course of treatment. Case Description Our case is an 82-year-old male with a history of cutaneous BCC on the arms and trunk presenting with a symptomatic perianal lesion. Initial biopsy demonstrated BCC with subsequent IHC studies differentiating from basaloid SCC. Standard treatment includes wide local excision (WLE) but given his poor performance status, radiation only was recommended. He was successfully treated and tolerated 30 Gy in 5 daily fractions. Conclusions Radiation only is a unique and feasible non-surgical treatment for basosquamous carcinoma of the anus.

A rare case of benign vulvovaginal leiomyoma: Case report and literature review.

Project description:IntroductionSmooth muscle tumors of the vulva are more difficult to diagnose and are frequently mistaken as Bartholin cysts prior to surgery.Case presentationA 41-year-old female presented with a left vulvar mass that increased in size compared to the previous year. The patient had normal urination and a regular menstrual cycle. The presentation was not associated with dyspareunia, abnormal bleeding, and signs of infection (e.g., fever, vaginal discharge). The history of any sexually transmitted disease was inconclusive. There was also no family history of malignancy. Physical examination showed a solitary swelling mass, measuring 5 × 2 cm in the left labia majora at the site of the Bartholin gland. The mass was firm in consistency, partially movable, and non-tender with no inguinal lymphadenopathy. Histopathology after surgical removal revealed a benign vulvar leiomyoma.DiscussionLabia majora leiomyoma at the site of the Bartholin gland is rather uncommon. Some cases can develop into atypical leiomyoma or even leiomyosarcoma with local tissue infiltration.ConclusionIf the clinical picture is unusual, it is better to send the patient for ultrasound and MRI to exclude other causes followed by performing wide local surgical excision of the mass to allow proper histopathological and/or immunohistochemistry examination to differentiate between benign and malignant tumors.

Tailgut cyst, management of a rare perianal mass: a case report.

Project description:BackgroundA perianal mass has a wide range of possible diagnoses, including tailgut cysts. Tailgut cysts are congenital, and their development is slow. Because its most common placement is retro-rectal, it is extremely rare to find it on the perianal level only. It is possible to develop neoplastic or infectious problems. Consequently, proper support is required.Case descriptionWe present a case of perianal tailgut cyst in a 59-year-old man who sought help for painless anal discomfort. Nuclear magnetic resonance was used to conduct this assessment. The radiologist thought it was probably benign, but he was not able to find a precise diagnosis. Thus, the cyst was completely removed using a transanal way with the patient in a lithotomy position. Then, the anatomopathological examination had confirmed the diagnosis and the benignity of the cyst. The postoperative follow-up was uneventful. We had planned to see the patient for a clinical follow-up every six months, but he has refused so far.ConclusionsTailgut cysts are uncommon in the perianal area but should be included in the differential diagnosis of perianal masses and should not be confused with an abscess or a haemorrhoid. The nuclear magnetic resonance appears to be the most appropriate radiological examination for the assessment of these masses. Excision is performed systematically to confirm the diagnosis and exclude a malignant condition thanks to the anatomopathological examination.

Contribution of imaging modalities to eosinophilic myocarditis diagnosis: a case report.

Project description:BackgroundEosinophilic myocarditis (EM) is a relatively rare form of myocarditis that could progress to restrictive cardiomyopathy and might be fatal if left untreated. Although myocardial biopsy is considered to be the gold standard for the diagnosis of myocarditis, its use in paediatrics remains controversial and not easily applicable in routine practice.Case summaryA 10-year-old girl with no prior medical history presented to the emergency department for fever, odynophagia, and gastrointestinal symptoms despite 48 h of antibiotics (Cefaclor). Physical examination revealed diffuse petechiae and abdominal tenderness but was otherwise unremarkable. Her vital signs were normal. She was found to have hypereosinophilia and increased cardiac markers on laboratory testing. Echocardiography showed diffuse left ventricular (LV) myocardial infiltrates, moderate LV dilatation, and mild systolic dysfunction. Bone marrow biopsy confirmed B cell acute lymphoblastic leukaemia. The diagnosis of EM was made. High doses of steroids and chemotherapy were initiated. Cardiac magnetic resonance imaging (MRI) identified eosinophilic infiltrates and sub-endocardial enhancement strongly suggestive of EM. Left ventricular function was slightly decreased. Intra-ventricular micro-thrombi were suspected, and warfarin was started. The outcome was favourable. Leucocyte and eosinophil counts were normalized within a month. At 6 months, cardiac MRI demonstrated a significant decrease in eosinophilic infiltration and micro-thrombi, normalization of LV function, and of sub-endocardial enhancement.DiscussionThis case demonstrates that non-invasive multi-modality imaging along with typical laboratory and clinical findings allow for appropriate diagnosis of EM while avoiding biopsy. It also highlights that an early diagnosis, timely treatment, and rigorous follow-up improve disease progression and outcome.

Case report: cotyledonoid dissecting leiomyoma in a 49-year-old woman.

Project description:BackgroundCotyledonoid dissecting leiomyoma (CDL) is much less common than typical leiomyoma. Macroscopically, it displays multinodular, exophytic, placenta-like cystic masses and extends into the broad ligament, pelvic cavity, and retroperitoneal space. The seemingly malignant gross appearance of the tumor has perplexed gynecologists and pathologists; microscopically, it has no malignant characteristics, such as atypical cells, a high mitotic index, or tumor necrosis. To date, only a few cases of CDL have been reported. Here, we report a case of CDL, highlighting its gross and histological appearance, and present a review of the literature.Case descriptionA 49-year-old woman presented with a history of progressive constipation of 6 months' duration and a palpable left lower abdominal mass of 1 month's duration. Transvaginal ultrasound revealed a bulky uterus containing 2 subserosal fibroids measuring 9.9 cm × 6.9 cm × 6.3 cm and 8.1 cm × 6.6 cm × 6.8 cm, respectively. An abdominal modified radical hysterectomy and bilateral salpingo-oophorectomy was performed. An intraoperative frozen section showed an angioleiomyoma with edema. However, the postoperative paraffin section confirmed a diagnosis of CDL. No abnormalities were observed at the 6-month follow-up visit.ConclusionsDespite its seemingly malignant gross appearance, CDL, based on its microscopic appearance, is a rare benign tumor and has a favorable prognosis.
