Case Discussion

60 year old diabetic patient. Presented with non-painful, pustular skin lesions localized to flexor surface of forearm (picture taken after patient's PCP drained lesions). Patient states "this is the first time" for him and reports no associated symptoms. Patient is afebrile and physical exam is unremarkable. What are some possible differentials? Thank you.

  2. Female 70 years old with no relevant history, lesion of 2 months approx in arm and recent lesion in eyebrow. Currently, both lesions are observed after a treatment with clindamycin 300mg VO c / 8Hrs for 10 days, Mupirocin salve with 8Hrs for 10 days and Ascorbic Acid 1gr c / 24Hrs for 10 days. What opinion do you have about it?

One month later a verrucous , crusted lesion with central ulceration developed in the elbow. Patient comes from the jungle. HAART: TDF/3TV/EFV. A giemsa stain was positive for leishmania sp. Patient was started on daily IV sodium stibogluconate. At 6th day of treatment lesion seems to get better. Is it possible for this to be a case of cutaneous leishmaniasis IRIS (uncover)?
