A 50-year old man with a history of metastatic mucinous appendiceal adenocarcinoma presented for evaluation of a desquamating rash on his face that had spread to his scalp, inguinal region, and perineum over the past 4 months. The rash was accompanied by diffuse alopecia of the face, scalp, axillae, and groin (Figure). There was no improvement in the rash despite multiple rounds of oral fluconazole, topical antibiotic ointment, and intravenous antibiotics. Prior to development of the rash, he completed neoadjuvant chemotherapy followed by surgical resection. He underwent colostomy after unsuccessful surgical correction for an enterocutaneous fistula and had required total parenteral nutrition (TPN) for the past year. He had not noticed any significant changes in ostomy output during this time.
