Storiform collagenoma of the nail.

The term circumscribed storiform collagenoma was coined by Maize et al in 1989 to describe four dermal fibromas with pathologic features resembling the sclerotic fibromas associated with Cowden's disease. We report a subungual nodule with the pathologic features of circumscribed storiform collagenoma in a patient without Cowden's disease.     

Pigmented Storiform Neurofibroma

A case of pigmented storiform neurofibroma (PSN) is presented. The lesion was present in the shoulder of a 7-year-old black girl and recurred after 10 years. The characteristic storiform pattern and melanin production are the relevant features for histologic diagnosis. The histogenesis and taxonomic position of this lesion is discussed with emphasis on its relationship with dermatofibro-sarcoma protuberans (DFSP) and cellular blue nevus.     

Eruptive collagenoma

A case of eruptive collagenoma in a male is being reported. He presented with asymptomatic nodules and plaques over the trunk, upper extremity and face of 15 years duration. Family history was negative. Histopathology with H & E stain followed by Verhoeff van Gieson's staining revealed increased collagen in dermis confirming the diagnosis of eruptive collagenoma. Patient also had Beckers naevus.     

Pacinian collagenoma

An unusual histological variant of collagenoma is described. A 36-year-old woman presented with a lump in the left hypothenar eminence. Histological examination revealed a well-delineated lesion composed of paucicellular collagen fibres arranged in concentric lamellations giving rise to an onion skin appearance. The overlying epidermis was thin and the lateral borders were demarcated by an epidermal collarette. Inflammation and xanthoma cells were absent and occasional capillaries were present. The lesion was positive for collagen stains, reticulin and CD34. This lesion represents an uncommon histological form of collagenoma or fibroma. It can be distinguished from histological look-alikes on the basis of the characteristic morphology and immunophenotype.
