Erythema nodosum migrans (subacute nodular migratory panniculitis) is a panniculitis characterized by migrating subcutaneous nodules or plaque on the lower extremity. We describe a 75-year-old woman with idiopathic erythema nodosum migrans which was manifest centrifugally spreading, slightly morpheaform erythematous plaque on the lower left leg successfully treated with indomethacin. She was initially diagnosed and treated as a case with cellulitis and with poor clinical response. A biopsy specimen from this lesion showed that the septal was thickening; fibrous tissue was also seen with lymphohistiocytic infiltrate and occasional multinucleated giant cells with some inflammatory cells infiltrated into the periphery of the fat lobules. Erythema nodosum migrans should be kept in mind in the differential diagnosis of any morpheaform centrifugally expended plaque, especially in the lower extremities in cases of unknown etiology.

Cutaneous larva migrans (CLM), a serpiginous cutaneous eruption is the most commonly acquired tropical dermatosis. It is caused by infection with hookworm larvae in tropical and sub-tropical areas, and people who have a history of travel in these countries. The most frequent location of CLM is the distal lower extremities or buttocks. We describe a case of 57-year-old Iranian female patient with CLM of hand (unusual site) without traveling to endemic countries that was successfully treated with oral albendazole. To the best of our knowledge, this is the first report of CLM in Iran.

We report a case of a 55-year-old woman, who presented with a vague pelvic pain and was found to have an ectopic pelvic kidney involved by a mass. Preoperative assessment was done by multi-slice CT and 3D-CT angiography. According to our knowledge only eight cases of pelvic kidney tumor have been reported in the literature and our case is the first report of using multi-slice CT and 3D-CT angiography in the preoperative evaluation of these cases.
