Reconstruction Approach to a Rare Case of Acquired Scrotal Giant Muscular Hamartoma.

ABSTRACT

Acquired scrotal giant muscular hamartoma is an uncommon benign lesion with fewer than 10 documented cases all over the world. It is characterized by a proliferation of dermal smooth muscle bundles of scrotum dartos fascia. The authors report a rare case of acquired scrotal giant muscular hamartoma, which occurred in a 70-year-old severely obese and diabetic man presenting with a progressive scrotal enlargement and swelling in the last year, causing marked reduction in quality of life and cosmetic problems. The patient underwent a wide excision of the hamartomatous lesion, and then, a reductive scrotoplasty and autologous skin grafting of penis were performed. Anatomopathological examination showed an acquired scrotal giant muscular hamartoma arising from muscular fascia of dartos. This surgical technique is a valid, safe, effective, and minimally invasive option to treat this pathology, achieving both excellent functional and aesthetic results, with a marked improvement of the patient's quality of life.
