Cutaneous leishmaniasis is a neglected tropical disease affecting mostly the exposed skin, causing severe and disfiguring lesions in Ethiopia. In this report, we present two cases of atypical mucocutaneous leishmaniasis; one HIV positive and one HIV negative patient. Cases . A 32-year-old male HIV patient presented with 40 days of bleeding per-rectum and a perianal lesion of 5 years. An erythematous nontender plaque measuring 5 cm by 5 cm was observed over the right perianal area with circumferential constricting firm swelling of the rectum. The patient was cured with AmBisome and miltefosine after an incisional biopsy revealed leishmaniasis. A 40-year-old presented with bleeding per-rectum and stool incontinence of 3 months, generalized body swelling of 2 months, and mass around his anus for ten years. A 6 by 3 cm indurated ulcerating mass surrounding the anus and a fungating circumferential mass of 8 cm were seen above the proximal anal verge. An excisional biopsy revealed leishmaniasis, and the patient was treated with AmBisome but passed away due to complications with colostomy diarrhea. Conclusion . Clinicians should consider atypical mucocutaneous leishmaniasis as a possible diagnosis in patients with chronic skin lesions resembling hemorrhoids and colorectal masses, especially in endemic areas such as Ethiopia, regardless of their HIV status.
