# Primary umbilical malignant melanoma requiring full-thickness abdominal wall resection and reconstruction with autologous fascia lata: a case report

## TL;DR

A rare case of umbilical melanoma was treated with full abdominal wall removal and reconstruction using the patient's own fascia lata, with no recurrence or hernia after one year.

## Contribution

This case report presents a successful use of autologous fascia lata for abdominal wall reconstruction after extensive umbilical melanoma resection.

## Key findings

- The patient had no local recurrence or hernia at 6-month follow-up.
- At one year post-surgery, no herniation or recurrence was observed.
- Autologous fascia lata graft provided effective reconstruction after oncologic resection.

## Abstract

Primary malignant melanoma of the umbilicus is extremely rare; evidence guiding optimal resection and reconstruction is limited. A 47-year-old man with primary umbilical melanoma underwent full-thickness abdominal wall resection including the peritoneum. The abdominal wall defect was reconstructed using an autologous fascia lata graft. Histopathology confirmed malignant melanoma with a tumor thickness of 18 mm (pT4bN1aM0, Stage IIIC). At 6-month follow-up, no local recurrence or incisional hernia was observed, and at one year after surgery, no evidence of herniation or recurrence was noted. Autologous fascia lata offers a practical option for abdominal wall reconstruction after extensive oncologic resection of the umbilical region, achieving early freedom from recurrence and hernia in this case.
