Fibrous tumors
Published in Eckart Haneke, Histopathology of the NailOnychopathology, 2017
Storiform collagenoma, also termed sclerotic fibroma or plywood fibroma, is a rare form of dermal fibroma arising spontaneously7 or in association with Cowden's syndrome.8,9 It mainly occurs in young and middle-aged adults and grows slowly to a size of approximately 1 cm in diameter. It may be a variant of fibrous histiocytoma although collagen I synthesis suggests a fibroblastic origin.10 Occurrence in the nail has been described.11
Benign tumors

This rare form of dermal fibromas is also called sclerotic fibroma or plywood fibroma. It occurs spontaneously102 or in association with Cowden’s syndrome103,104 and is mainly observed in young and middle-aged adults. It grows slowly and does not exceed a diameter of 1 cm. It is rare in the nail.105 It needs to be distinguished from other types of fibromas, particularly old sclerotic histiocytoma.

Sclerotic fibroma (SF) is an uncommon yet benign tumor associated with Cowden’s disease that presents as an asymptomatic, well-circumscribed, raised lesion.1,2 Histologically, it is characterized by a well-demarcated but nonencapsulated, dermal nodule comprising bland spindle cells, with an often storiform pattern and hypocellular sclerotic collagen bundles with prominent clefting.3 We describe a patient presenting with an eyelid nodule initially treated as a chalazion, which was found to be a rare case of a solitary SF of the palpebral conjunctiva on histopathological examination. While solitary SFs have been described affecting head and neck mucosa, we report the first case of its presentation within conjunctiva.4
