Partial agenesis of the pectoralis major and minor muscle: A cadaveric case report.

ABSTRACT:

Rationale

The pectoralis major and minor muscles, located in the anterior chest wall, are crucial for upper limb movements.

Patient concerns

Their nonsyndromic absence is rare but significant for surgical procedures involving the axillary and pectoral regions.

Diagnoses

The study was conducted at the Human Anatomy Laboratory of the School of Medicine of the Universidad Finis Terrae in Santiago, Chile, in August 2022.
