Myxoma is a rare, benign stromal tumor of mesenchymal origin often confused with other conjunctival stromal tumors. Conjunctival myxomas are thought to originate in Tenon's capsule and can masquerade as conjunctival lymphoma, lymphangioma, ocular surface squamous neoplasia (OSSN), or amelanotic melanoma.
Superficial acral fibromyxoma impacts the palm, heel, and ankle in addition to the acral regions, with a clear preference for the periungual and subungual regions of the fingers and toes. [2] It begins as a slow-growing, solitary nodule limited to the dermis and subcutaneous tissue , and it is typically painless. [ 3 ]
Superficial acral fibromyxoma, also termed acral fibromyxoma. [15] Gardner fibroma, a benign proliferation of thick, irregularly arranged collagen bundles with interspersed fibroblasts often association with the genetic disease of familial adenomatous polyposis [23] and its variant, the Gardner's syndrome.

Acral angifibromeae occur primarily in areas close to the nails of fingers and toes (~80% of cases) [28] or, less commonly, palms of the hands or soles of the feet. [14] The tissues of this tumor consists of bland spindle-shaped and star-shaped cells within a collagen fiber -rich stroma containing prominent blood vessels and mast cells .
AMSF tumors typically occur in adults (average age: 40 years), [4] but have been reported in individuals aged 4 to 91 years. [7] Individuals commonly present with a subcutaneous [5] or less commonly intramuscular [2] tumor located in an acral (i.e. distal), dorsal (i.e. posterior side) of a limb: about two-thirds of cases occur in a finger, hand, wrist, foot, or ankle. [4]
Cutaneous myxoma appears as a little, slowly expanding dermal or subcutaneous lump that typically affects adults' heads and necks. [3] Alopecic lesions have been reported, [4] [5] characterized by hair tufts overlaying the lesion or even hypertrichosis. [6]
