Cellular variant of benign fibrous histiocytoma: A case report

Benign fibrous histiocytoma or dermatofibroma is one of the most common types of benign, cutaneous, soft tissue tumors, most often found in the middle-aged adults. The diagnosis of dermatofibroma/benign fibrous histiocytoma is usually straightforward if the typical morphological features are present. However, some diagnostic difficulties may arise when one is dealing with some unusual morphological variants. Among these variants, cellular fibrous histiocytoma (CFH) may represent a diagnostic challenge because there is a risk of it being confused with other benign or malignant dermal tumours. Careful histopathological examination with the clear knowledge of this variant is important to avoid a misdiagnosis of a possibly more aggressive tumor. We are hereby briefly highlighting the intriguing nature of cellular benign fibrous histiocytoma with which we have encountered.
