Case in brief
A man with pulmonary tuberculosis presented with a crateriform facial nodule. Upon investigation, the lesion was identified as cutaneous cryptococcosis, a rare manifestation typically resulting from hematogenous spread. The nodule's distinct central umbilical notch was a key feature that guided the diagnosis. The patient was treated appropriately, leading to resolution of the skin lesion.
What made this case unusual
The presence of a crateriform nodule with a central umbilical notch is an atypical presentation of cutaneous cryptococcosis, which can often mimic other skin disorders.
Diagnostic / clinical pearl
Clinicians should carefully examine skin lesions, particularly those with unique features like a central umbilical notch, to consider cutaneous cryptococcosis in patients with a history of pulmonary infections.
Why it matters
This case underscores the importance of thorough skin examinations and relevant investigations in patients with systemic infections, as cutaneous manifestations can be misleading.
