Rapidly progressing necrotic hand ulcer in a patient with angioimmunoblastic T‐cell lymphoma

Mucormycosis is a fungal infection caused by opportunistic fungi of the phylum Glomeromycota, subphylum Mucormycotina. In developed countries, it affects patients with haematological malignancies undergoing chemotherapy and those who have received allogenic stem cell transplants, while in developing countries it is seen in those with uncontrolled diabetes mellitus. Herein, we report a case of cutaneous mucormycosis in a 67yo Chinese gentleman with background of angioimmunoblastic T cell lymphoma (AITL) on chemotherapy. We also share the clinicopathological findings of this and correlate these findings with those present in the current literature. Finally, we outline treatment options and prognosis of cutaneous mucormycosis.
