Case Report: A Single-Center Case Series on Skin Manifestations of Leishmaniasis from a Non-Endemic State in Southern India.

Leishmaniasis is endemic in the Indian subcontinent with predominance of visceral leishmaniasis (VL) due to Leishmania donovani. Cutaneous leishmaniasis (CL) is uncommon, and mucocutaneous leishmaniasis (MCL) is rarely reported in this region. Recent reports reveal a changing epidemiology and atypical manifestations. A retrospective study of 52 suspected cases with cutaneous and mucosal involvement seen from January 2008 to December 2018 in a tertiary care setting in a non-endemic state in southern India is reported. Twelve patients were confirmed to have leishmaniasis; seven had MCL, two had CL, and three had post-kala-azar dermal leishmaniasis (PKDL). All cases were male, with a median age of 41.5 years (interquartile range, 30-55.5 years), and the median duration of the disease was 6 years (interquartile range, 1-9.5 years). Patients with MCL had mucosal involvement including destructive ulcero-proliferative lesions due to delayed diagnosis; none had a history of travel to countries endemic for MCL and all were attributable to L. donovani species. On the other hand, Leishmania major which was the causative species in both CL patients was associated with travel to the Middle East. Patients with PKDL presented with multiple plaques and hypopigmented patches; one had concomitant VL and all were from endemic areas. Hitherto uncommon MCL, caused by potentially atypical variants of L. donovani, has emerged as a new manifestation of leishmaniasis in this region. A high index of suspicion based on lesions seen and history of travel combined with PCR-based diagnostics are required to confirm diagnosis for the various skin manifestations of leishmaniasis.

Solitary Angiokeratoma Presenting as Cutaneous Horn over the Prepuce: A Rare Appearance.

We present a case of a 47-year-old man with 4 months history of conical growth on the prepuce with a progressive increase in size. The patient had been treated for seminoma a decade ago. Histopathology of the growth showed features of angiokeratoma. It is unusual for angiokeratoma to masquerade as a cutaneous horn.

Bullous Fixed Drug Eruption Probably Induced by Paracetamol.

We report a case of a 42-year-old male who presented with second episode of bullous eruptions after ingestion of paracetamol. There were no systemic complaints. The temporal correlation with the drug, history of a similar episode and the quick improvement led us to a diagnosis of bullous fixed drug due to paracetamol. Applying Naranjo's algorithm, a causality score of 8 was obtained and was categorized as probable reaction to paracetamol. Clinicians should be vigilant of the possible adverse reactions to drugs with robust safety profiles. Drug alert cards could play an important role in preventing recurrences.
