| Popis: | Intraneural perineurioma is a rare lesion of the peripheral nervous system with unique ultrastructural features, and it is distinct from Schwann cell-derived entities (schwannoma and neurofibroma). The present case aims to report a lesion in the lower lip in a 33-year-old female patient. Clinical examination showed a nodular growth, sessile, and smooth surfaced from an undetermined etiology. Histopathologic examination revealed slender spindle cells, arranged in 2 fascicles, and focal areas showing a distinct storiform pattern, surrounding by histiocytes. Histopathologic investigation comprised of toluidine blue, Masson trichrome, and picrosirius red showed presence of mast cells, collagen organization, and type III prevalence. Based on clinical and histopathologic findings, the final diagnosis was intraneural perineurioma. Eight-month follow-up showed no recurrence. We will discuss histopathologic and histochemical aspects of interest for intraneural perineurioma diagnosis. |
