A Crateriform Facial Nodule in a Man With Pulmonary Tuberculosis.

Cryptococcus neoformans is an environmental pathogenic yeast which causes both life-threatening infection and mild, localized infection. Cutaneous cryptococcosis is an uncommon event that usually results from haematogenous dissemination after a primary infection in the pulmonary or other organs, although primary cutaneous infection is possible. The lesions of cutaneous cryptococcosis are not pathognomonic, varying from nodules to ulcers and plaques, and thus can mimic other skin disorders. This case highlights that clinicians need to observe the skin lesions carefully and improve the relevant investigations when encountering this type of rash with a central umbilical notch.
