“…Macroscopically, the present case did not involve a polypoid tumor, but rather an elevated lesion that was black in color. Primary malignant urethral melanomas in females tend to metastasize to adjacent areas at an early stage, including the regional lymph nodes and occasionally distant sites via the hematogenous route [16]. In this case, we found inguinal lymph node metastasis 16 months after surgery.…”

We herein report a rare case of primary malignant urethral melanoma developed in an elderly Japanese patient with hypertension, diabetes and hyperlipidemia. An 80-year-old female presented at our hospital with a history of urodynia and perineal pain lasting for several months. Cystoscopy revealed cystitis and urethritis with erosion. At that time, urinary cytology was negative for malignancy, although melanophages were observed. Four months later, lower abdominal computed tomography and magnetic resonance imaging indicated urethral tumors. Urinary cytology subsequently detected malignant melanoma, and a biopsy of the urethra confirmed malignancy. Although inguinal lymph node metastasis was found 16 months postoperatively, the patient has remained free of disease for more than six years after surgery and chemotherapy.

“…Melanoma develops by malignant transformation of melanocytes and commonly originates from the skin. It also less commonly originates from the retina, digestive tract, liver, upper respiratory tract, lung, urethra and prostate (10)(11)(12)(13)(14)(15). Although pleural metastasis from cutaneous melanoma is relatively common, primary pleural melanoma is extremely rare.…”

Primary Pleural Melanoma: A Case Report and Literature Review

et al. 2019

Primary pleural melanoma is an extremely rare neoplasm, and to the best of our knowledge, there have been only 8 case reports of this condition in the English literature. We herein report a rare case in which the cytological and immunocytochemical analyses of pleural fluid and ultrasonography (US)-guided biopsy of a pleural lesion were useful for the diagnosis primary pleural melanoma. This case highlights the importance of careful physical examinations, cytomorphologic and immunocytochemical analyses of pleural fluid, as well as the utility of US-guided biopsy of the pleural lesions in the diagnosis of primary pleural melanoma.

“…It is a rare malignancy and accounts for 0.2% of all malignant melanomas and 4% of all urethral cancers. [3] Till date around 121 cases of female urethral malignant melanoma have been reported. [4] www.pacificejournals.com/apalm eISSN: 2349-6983; pISSN: 2394-6466…”
