Extra-Abdominal Fibromatosis of the Cheek: Report of a Case

Congenital infantile fibromatosis of the cheek: report of a rare case and differential diagnosis

Infantile fibromatosis is a benign tumour that consists of dense masses of fibroblasts and myofibroblasts with marked collagen production. Although it is a nonmetastasising tumour, it has significant potential for local invasion and recurrence and may be fatal because of its size and location. The authors report an unusual case of infantile fibromatosis of the cheek in an 8-month-old boy, present since birth. The patient underwent surgical treatment with tumour-free margins and the 6-month follow-up revealed no signs of recurrence. Infantile fibromatosis of the cheek is a very rare condition at this location, especially congenital cases. It should be considered in the differential diagnosis of congenital lesions in childhood.

Tendon sheath fibroma of the medial canthus

Isolated fibromas of the ocular adnexa are rare. Fibromas of the tendon sheath (FTS) are benign, collagenous, spindle cell neoplasms that typically present as an acquired, painless mass in the adult extremities. They infrequently involve the head and neck. We report a case of FTS presenting as a medial canthal mass. Like most FTS, the lesion in our patient was successfully treated by complete surgical excision. While the differential diagnosis contains a variety of mesenchymal tumors, the clinical and radiographic characteristics should lead to the correct diagnosis. To our knowledge, this is the first case of FTS reported to arise at this site.
