RESUMO
BACKGROUND: Sparganosis is not a common disease, and its rarity makes it difficult to distinguish from others. Close examination of fine needle aspiration biopsy (FNAB) samples, however, can aid in histologic examination of the lesion. CASE: A 64-year-old female, born and raised in a rural area in the state of Goiás, Brazil, presented with a relatively mobile and hard lump in the lower inner quadrant of the right breast. It was initially diagnosed as granulomatous mastitis, but cytologic examination of the surgical specimen revealed a sparganum larva, also revealed by anterior FNAB. CONCLUSION: Sparganum should be considered in the differential diagnosis of granulomatous mastitis, especially among Asians living in other countries.

The authors studied a species of Leishmania which is the causative agent of cutaneous leishmaniasis in Mato Grosso, Brazil. The parasite displays unusual characteristics which do not fit exactly into either the L. mexicana or L. brasiliensis complexes. The buoyant density DNA resembles that of the L. mexicana complex but the culture and hamster inoculation results resemble those of the L. brasiliensis complex. Further comparative studies are required to elucidate the relationship of the Mato Grosso Leishmania to the L. mexicana complex.
