Disseminated cutaneous rhinosporidiomas in an immunocompetent male.

Rhinosporidiosis is a chronic recurrent infective granulomatous disease of man and animals. It is endemic in India and Sri Lanka. Rhinosporidiosis is a chronic disease commonly involving the nose and nasopharynx. Cutaneous lesions, although rare, can occur due to autoinoculation or due to hematogenous spread. However, disseminated cutaneous lesions presenting as tumor-like swellings are rare. We report here a 48-year-old immunocompetent patient who had disseminated painless cutaneous tumor-like swellings over both the upper limbs, abdomen, left buttock and calf since 10 months, gradually increasing in size. On inquiring, the patient gave history of excisions and electrocauterization of subglottic and nasal polyps. Histopathological examination of these lesions was suggestive of rhinosporidiosis. The general and systemic examinations of the patient did not reveal any abnormality.

An intramuscular cysticercosis, a case report with correlation of magnetic resonance imaging and histopathology.

The authors report a case of a solitary intramuscular cysticercosis in a 47-year-old female who presented with a mass in the right elbow for five years. The magnetic resonance imaging (MRI) findings revealed a cystic mass of 1.5 cm. in size located at the periphery of the pronator teres muscle; the T1-weighted MRI showed hypointensity mass with internal content that was more obviously seen on T2-weighted image and T1-weighted with fat suppression after gadolinium administration. The authors could not recognize perilesional edema in the MRI that corresponded with the histological findings of chronic inflammatory process in combination with foreign body giant cell reaction. The scolex could not be seen in the imaging but could be identified in the histopathological sections.

New World cutaneous leishmaniasis imported into Australia.

A case of cutaneous leishmaniasis in a traveller from Belize, Central America is reported. Leishmaniasis presents rarely in Australia and delays in diagnosis and treatment often occur. A high index of suspicion in a patient who has returned from an endemic region is required. Subsequent confirmation of a diagnosis of cutaneous leishmaniasis is best achieved by demonstration of the organism on skin biopsy, aspiration or smear. The histology is variable and depends on geographic, parasite species and host factors. Speciation of New World disease as either Leishmania braziliensis or Leishmania mexicana is important to determine the risk of later development of mucosal disease, which normally only occurs with L. braziliensis infection, and for optimal treatment. Several different modes of treatment have been suggested, but antimonials, such as sodium stibogluconate, remain the treatment of choice in New World cutaneous leishmaniasis.
