ABSTRACT
Rhinosporidiosis is a chronic granulomatous disease caused by Rhinosporidium seeberi. It usually occurs in the mucous membranes of nose, nasopharynx, and eyes, and less commonly in extra nasal sites such as skin, bones, genitalia, and even the internal organs. Rhinosporidiosis occurs in the wrist joint with isolated bony involvement is rare. We report one such case in a 50-year-old man who presented with a non-tender, fixed swelling over his anterolateral aspect of left forearm. Radiography and computed tomography showed a lytic destructive lesion involving the distal radius, ulna, carpals, and base of metacarpals. Biopsy revealed features of rhinosporidiosis. The patient underwent below-elbow amputation.

Contrary to the popular perception, hydatosis does not remain restricted to certain geographical locales but is a global health concern, particularly in the rural countryside. Although liver and lung involvement account for the majority of the lesions, primary breast, bone, kidney and soft tissue hydatosis with features of cystic echinococcosis are extremely rare. We report four such rare cases of cystic echinococcosis which were diagnosed and treated in our institute.

Wild Japanese serows (Capricornis crispus) were found to have parasitic lesions in tendons that attached the musculus tricepus brachii to the olecranon. Histopathological study of the lesions showed chronic tendinitis with multiple granulation nodules around the worms. The lesions were found in 138 of the 353 serows examined and were more frequent in aged animals than young ones. Transverse ridges on the cuticle of the female midbody, the sizes and morphological features of the spicules, and the arrangement of the caudal papillae of the males showed the parasite to be Onchocerca skrjabini. Therefore, O. skrjabini causes olecranon lesions in addition to fibrous bursa formation in carpal and tarsal regions of the Japanese serows.
