Rhabdomyosarcoma (RMS) comprises 3% of all childhood malignancy. Commonly it involves head and neck, extremity and genitourinary systems. Pure primary RMS of breast is a rare malignacy. Here, we present a case of adolescent girl presented with breast lump which was initially treated as benign lesion with excision. Again she presented with recurrent mass which was operated and microscopically showed features of small blue round cell tumour which has lead to many diagnostic confusions both clinically and histopathologically. Immunohistochemistry with strong nuclear myogenin positivity in >50% of tumour cells confirms the diagnosis of primary mammary RMS. Postoperative period was uneventful. [ABSTRACT FROM AUTHOR]

Intra articular synovial lipomas are very rare and only few cases have been reported till now. We are reporting a rare case of intra articular synovial lipoma of the tarsometatarsal joint in the right foot in a 38-year-old male who presented with dull aching pain in the plantar aspect of the foot while walking. The lesion was resected and subjected to histopathological examination, which showed well defined lobules of mature adipocytes separated by thin fibrous septa and covered by synovial lining. Immunohistochemistry with S100 antigen showed membrane positivity. A diagnosis of intra articular synovial lipoma of the tarsometatarsal joint of the right foot was made. Our English literature search failed to yield any information regarding the occurrence of synovial lipoma in small joints and our case may be the first of its kind. [ABSTRACT FROM AUTHOR]
