Carcinoma En Cuirasse of Scrotum–-Metastatic Malignancy from a Lung Primary

Abstract

A 69 year old male who presented with painful, swollen and infl amed scrotum is presented as a unique case report. He was initially treated as a case of infection and was subject to further investigation due to poor response to antibiotics. CT scan showed thickened scrotal wall and an incision biopsy revealed metastatic 'carcinoma en cuirasse' of the scrotal wall with the primary foci in the lung. There has been one other such case reported in literature, presenting as generalised swelling of scrotum with the whole of the scrotal wall being involved.

Scrotal wall metastasis from a primary lung adenocarcinoma

“…A review of the literature could only identify sporadic cases of paratesticular metastasis, the primaries being from malignant melanoma, anal carcinoma, renal cell carcinoma [7] , transitional cell carcinoma [8,9] , gastric and colorectal carcinoma [10–12] , desmoplastic small cell tumor [13] , signet ring cell carcinoma [14] , adenocarcinoma of prostate [15] . Among those we found only four cases of primary lung carcinoma: two presented as painful scrotal wall thickening (carcinoma en Cuirasse) [16,17] , the third one was described as a left scrotal mass in the inner layers of the scrotal wall, separate from the left testicle, epididymis and spermatic cord [18] , the fourth case was a metastatic scrotal tumor from a lung adenocarcinoma with a micropapillary component [19] .…”
