CASE REPORT : A RARE CASE OF CUTANEOUS DESMOID-TYPE FIBROMATOSIS

Desmoid fibromatosis (DF) is a rare, locally aggressive connective tissue malignancy primarily affecting musculoaponeurotic tissues, representing less than 3% of all neoplasms. This case report presents a 30-year-old male with cutaneous desmoid fibromatosis, a rare variant characterized by a painless, firm mass in the left shoulder region. Histopathological, immunohistochemical, and molecular analyses confirmed the diagnosis of desmoid cutaneous fibromatosis, with positive findings for nuclear beta-catenin. Management involved a multidisciplinary approach, with a conservative strategy due to the tumors size and location, emphasizing regular monitoring for recurrence. Differential diagnosis considerations included dermatomyofibroma and scar tissue. Treatment options for DF vary, with a shift towards observation as the primary strategy, particularly in cases where surgery may result in significant functional impairment. Medical treatment or surgery may be considered in symptomatic or progressive cases. Close surveillance and follow-up imaging are crucial for early detection of disease progression. cutaneous desmoid fibromatosis presents diagnostic challenges, highlighting the importance of early identification and biopsy to prevent misdiagnosis.
