        A 35-year-old man presented with an asymptomatic, solitary, mushroom-like, firm, red, slightly crusted nodule on the abdominal wall of 3-4 months duration. He had no other complaint. Excisional biopsy revealed secondary plamacytoma (biopsy showed nodular and diffuse collections of plasma cells with varying degrees of pleomorphism and atypia). Further assessment by an oncologist with relevant investigations a hidden asymptomatic multiple myeloma was discovered.
