摘要

A 50-year-old man with diabetes mellitus with diabetic retinopathy, peripheral neuropathy, hypertension, and end-stage renal disease on maintenance hemodialysis, presented with persistent cough and hiccups, continued to be unwell with weight loss, poor appetite, and recurrent respiratory symptoms such as wheezing and cough. Whole body positron emission tomography-computed tomography scan showed metabolically active lesions in liver, stomach/lesser sac, pancreas, and left sixth rib. As he had repeated bilateral transudative pleural effusion, left mini thoracotomy with pleural biopsy showed no evidence of granuloma or malignancy. Upper gastroscopy showed tiny gastric polyp; biopsy revealed benign lesion. Left posterior rib biopsy from the lesion and iliac crest biopsy showed no evidence of malignancy or granuloma. Further evaluation showed plasma chromogranin A -5737g/L (<100g/L) with a repeat value of 6950g/L (<100g/L). He was initiated on oral sunitinib 25mg once a day and injection octreotide 20mg subcutaneously once a month. The plasma chromogranin A level and his symptoms, however, showed an initial improvement, but gradually worsened after 4 months despite being on treatment. After 6 months, the patient developed a gangrenous lesion of his glans penis with necrosis. Due to severe pain on conservative measures, penectomy with perineal urethrostomy was performed. Biopsy of the lesion showed blood vessels with intimal calcifications and thrombosis suggesting penile necrosis.
