Abstract:
Atypical fibrous histiocytoma (AFH) is an uncommon variant of benign skin neoplasm, fibrous histiocytoma. Despite having pseudosarcomatous histological features, atypical fibrous histiocytoma is characterized by a benign clinical course.
Aim:
The aim of the study was to present the case of local recurrence of atypical fibrous histiocytoma in scar after the primary excision.
A Case Report:
A 28-year-old woman was admitted due to a slowgrowing 10 mm skin tumor of the left elbow, which has been observed for 18 months. Physical examination revealed that the tumor was covered by normal skin, firm, painless and movable. Tumor was excised and the wound was healed properly. Histopathological examination revealed AFH with normal tissue margins below 1 mm. It was decided to increase the excision. After 4 months patient was admitted for an extended resection. Physical examination showed no abnormalities within the scar. Despite this the primary procedure was radicalized and the scar with margins was excised. Histopathological examination reveals a subcuticular, single-site, 2 mm recurrent atypical fibrous histiocytoma with a surrounding of 2-10 mm normal tissue margin. The patient remains in follow-up the scar reveals no irregularities. The excisional biopsy followed by an extended resection makes a complete recovery.
Conclusions:
The probability of a too small surgical margin (<1 mm) could contribute to the local recurrence of atypical fibrous histiocytoma.
