Solitary intrascrotal neurofibroma: A case diagnosed on aspiration cytology

Abstract

Solitary neurofibroma of the scrotum is exceedingly rare and very few cases of this unusual occurrance have been reported till date. None of the previously reported cases had a preoperative cytologic diagnosis. A young man presented with an eight-month history of right scrotal swelling. Fine-needle aspiration cytology showed a spindle cell tumor with fibrillary matrix and wavy slender nuclei. A cytologic diagnosis of benign nerve sheath tumor was rendered. The patient underwent surgical excision of the mass and histopathologic examination confirmed the diagnosis of a neurofibroma. This case is the first reported instance of aspiration cytologic diagnosis of intrascrotal neurofibroma. This rare tumor should be considered in the cytologic differential diagnoses of testicular and paratesticular tumors.

A case report of solitary neurofibroma of the Vas deferens

“…Isolated intrascrotal neurofibroma unrelated to NF–I is very rare. According to the literature review, only 14 cases are reported 1 . Here we report a confirmed case of neurofibroma of vas deferens.…”

Intrascrotal solitary neurofibroma: A case report and review of the literature

“…[3] Neurofibroma of scrotum in the absence of NF I is extremely rare and to the best of our knowledge, about 10 cases [Table 1] have been reported in the English literature so far. [2] Solitary scrotal neurofibroma of the scrotum has been reported in a wide range of ages, mostly presenting with painless or painful swelling of the scrotal area. [4–10]…”

“…[1] Solitary scrotal neurofibromas unassociated with neurofibromatosis type I (NF I) are extremely rare and to the best of our knowledge, only 10 cases have been reported in the English literature. [2] Herein, we report a patient with scrotal mass who was diagnosed as scrotal neurofibroma after pathologic examination.…”

A case of diffuse bilateral scrotal neurofibroma in a rabbit

“…Neurofibroma is a rare benign tumour of the scrotum, with less than 10 cases reported to date in humans (Issa et al 1993, Mishra et al 2002, Turkyilmaz et al 2004, Trovarelli et al 2006, Shibano et al 2010, Gupta et al 2011, Hosseini et al 2012. To the authors' knowledge, none have thus far been reported in animals.…”
