Squamous cell carcinoma of the penis and scrotum in a patient with chronic scrotal and penile lymphedema

Abstract: Squamous cell carcinoma arising from tissue affected by chronic lymphedema is rare, though it is recognized that a variety of malignant tumors can arise in chronic congenital or acquired lymphedema. We describe, a case of scrotal and penile squamous cell carcinoma arising in a patient with a history of chronic scrotal and penile lymphedema of filarial origin. We here discuss the management and possible etiology of this unusual case.

“…Other uncommon occurrences of SCC on pre-existing dermatological conditions, which have been reported from India include the following: lichen planus (LP)[ 44 ] including LP hypertrophicus,[ 45 ] necrobiosis lipoidica diabeticorum (NLD),[ 46 ] lichen simplex chronicus (LSC),[ 47 ] psoriasis,[ 48 ] chronic lymphedema,[ 49 ] and disseminated porokeratosis. [ 50 ] Various pathogenetic factors have been ascribed to the malignant transformation in these conditions, inter alia , hypoxic status of poorly vascularized cicatricial structures in NLD, chronically irritated skin of LSC, deficiency in afferent lymphatic drainage preventing early recognition of tumor-specific antigen in chronic lymphedema,[ 51 ] and overexpression of p53 in the keratinocytes near the cornoid lamella in the porokeratotic lesion.…”

“…Chronic stasis in lymphedema results in alterations in lymphatic protein composition, notably a decrease in the alpha-2 globulin fraction and an increased albumin-globulin ratio. These changes delay protein transportation from the interstitial space to the lymphatic tissue, affecting the tissue's antigenic composition and regional immunological competence [ [10] , [11] , [12] ]. In rare instances, chronic lymphedema can evolve into squamous cell carcinoma, with fewer than 20 cases documented in literature and merely 11 of these involving the lower limbs.…”

“…SCC has rarely been found to be associated with chronic lymphedema. So far, 4 congenital cases and 9 acquired cases, all arising in the extremities [ 7 , 8 ], as well as 3 cases with penoscrotal involvement [ 9 , 10 , 11 ], have been reported. To the best of our knowledge, this study is the first to report involvement of the labia.…”
