Giant onychomatricoma is a rare fibroepithelial nail matrix tumor with only two previous reports in literature, from Mexico. An 80-year-old female patient presented with a progressively painless mass in the left great toe nail, following trauma, of 2 years duration. On examination there was a single, hard, immobile mass of size 4 × 3 × 2 cm with proximal hyperpigmentation of the left great toe nail. The mass was totally excised and a punch biopsy of nail matrix was taken. Histopathology revealed hyperkeratosis, acanthosis, multiple channels lined by flattened epithelium and fibrocollagenous tissue in horizontal orientation in deeper layers. The patient had no recurrence after 1 month. We report this case for its rare and distinct clinical presentation, characteristic histopathology and easy surgical treatment.

First described in 1992, onychomatricoma is a rare, benign, fibroepithelial tumor of the nail matrix with few reported cases in the literature. The tumor predominately affects the fingers of Caucasian women during the 5th decade of life and is typically slow growing and painless. The authors present a unique clinical presentation of a giant onychomatricoma in a darker-skinned 60-year-old South Asian individual who presented with a large dome-shaped nail that was smooth, shiny, and green.

Onychomatricoma is a rare benign fibroepithelial filamentous tumor originating from the nail matrix. It typically presents with the clinical tetrad of xanthonychia, pachyonychia, proximal splinter hemorrhages and increased transverse overcurvature of the nail plate. The giant variant can easily confuse the clinician due to its extensive nail dystrophy that can mask the characteristic features of this tumor.
