[Epidemiological clinical and laboratory characterization of sporotrichosis in patients of a tertiary care hospital in Lima, Peru, from 1991 to 2014].

BACKGROUND

Sporothricosis is endemic in numerous Latin American countries and the rest of the world. In Peru is concentrated in regions with warm and humid climate being little known in the rest of the country.

AIM: To describe the epidemiological, clinical and laboratory characteristics of patients diagnosed of sporotrichosis in a tertiary-care level hospital in Lima, Peru from 1991 to 2014.

METHODS

This was a retrospective, case series.

RESULTS

Ninety four patients were involved; most of them were male adults. This condition was acquired more frequently in Cajamarca, Apurímac, and Amazonas. Fixed and lymphocutaneous form were the most frequent forms of presentation in adults and were mostly distributed in upper limbs. Lesions located in head and neck were most frequent in children. Comorbidities were present in 15% of patients and were more frequent in those who presented disseminated cutaneous form. Seventy eight percent of cultures from skin lesions were positive within 7 days. The time to positivity of cultures was longer if the sample came from skin biopsies than skin scraping or skin aspiration.

CONCLUSIONS

Most cases of sporotrichosis were acquired in areas of extreme poverty in Peru. The clinical, epidemiological and laboratory findings were similar to those reported elsewhere. The time to positivity of cultures varies based on the type of skin sample. This finding needs to be further evaluated in studies with an increased number of cases.
