Unusual malar rash with ulceration: What can we expect?
Abstract
Considering the clinical polymorphism of the disease, longstanding skin lesions located on the face, resembling erysipelas in an endemic area should always be investigated for CL and thus, atypical presentations should be kept in mind.
A 45-year-old Tunisian woman, with no medical history, presented with an infiltrative plaque of the face treated with a systemic antibiotic for 1 month with no significant response. Cutaneous examination revealed an erythematous infiltrate plaque covering the center of the face with an ulcerated center and extension to the cheeks. (Figure 1) The review of the underlying mucosa was normal. Dermoscopy showed multiple orange-red areas with diffuse erythema, linear vessels, and multiple yellow tears. (Figure 2).


Given the endemo-epidemic profile of our country, cutaneous leishmaniasis (CL) was suspected. Further evaluation by direct examination of the skin of the nose using lesion scraping by a vaccinostyle, under sterile conditions was performed (Giemsa staining). The smears detected intra and extracellular amastigote forms of Leishmania confirming the diagnosis of CL. The patient was treated with intramuscular meglumine antimoniate for 14 days with good evolution.
CL is a parasitic infection encountered in daily dermatologic practice. It has many different clinical presentations depending on the immune status of the host and subspecies of Leishmania.1 Erysipeloid CL is atypical and under-reported of leishmaniasis. It frequency in the literature is estimated between 0.005 and 3.2%.1 Several hypotheses have been suggested: hormonal disturbances associated with menopause, alteration of immunity and the quality of skin tissue linked to aging, and specific species involved.1 Recently, multiple dermoscopic features of CL have been described including erythema, yellow tears, starburst-like patterns, and vascular structures.2
