Abstract

We report a case of granular cell tumor, a rare neoplasm of the penis.

Granular cell tumor of the penis: clinicopathologic evaluation of 9 cases

“…Our findings together with data derived from the English-language literature indicate [14] 33/B Shaft 1.5 Simple excision NED/1 y Suarez and Lewis [15] 29/B Glans 2.0 Simple excision Lost to follow-up Tanaka et al [16] 8/A Corpus cavernosum 3.0 Simple excision NED/27 mo Bryant [11] 42/W Shaft 3.0 Simple excision NED/2 y Grotas et al [17] 5/NA Corona 7.0 Simple excision NED/1 mo Gardner and Goldberg [18] 47/W Corona 9.0 MMS NED/6 mo Carver et al [19] 53/NA Base of shaft 20.0 Simple excision NED/1 y Bulstrode et al [20] 17 that a simple surgical excision of histologically benign GCT is adequate treatment. Furthermore, patients with microscopically involved surgical margins can be clinically followed because no superficial GCT in this cosmetically sensitive area has been reported to recur after excision.…”

“…With the exception of 2 cases where the race of the individual was not provided [17,19], the men were white (n = 4) [11,13,18,20], black (n = 2) [14,15], or Asian (n = 1) [16]. Eight tumors arose in the superficial tissues of the penile shaft (n =3), glans (n= 2), corona (n =2), and prepuce (n= 1) and ranged in size from 1.5 to 25.0 mm (mean, 7.8 mm; median, 3.5 mm).…”

“…All tumors presented as asymptomatic lesions with gradual, continued growth reported in 3 cases. The microscopic description available for 7 of the tumors [11,14,[16][17][18][19][20] indicated that all of them exhibited conventional histology and possessed no atypical features.…”

“…Most GCTs reported in this anatomic region arose in the superficial tissues of the vulva and clitoris with nearly 60 examples of GCT documented in case reports and series (PubMed). In comparison, GCT of the male external genital tract is infrequently reported with only 3 scrotal [11,12] and 9 penile GCTs [11,[13][14][15][16][17][18][19][20] documented in the Englishlanguage literature.…”

Granular cell tumor of the urethra: a case report and literature review

“…In general, GCTs more commonly occur in the head and neck region with tongue being considered the most common site. However, GCTs of the male external genitalia, especially the penis ( Table 1 ),123789101112131415 have been rarely reported. Here, we report the first case of a GCT of the urethra in man.…”
