Schwannomas are benign nerve sheath tumors. Malignant schwannomas have been reported in literature but they frequently originate from the conversion of plexiform neurofibromatosis rather from the malignant degeneration of a benign schwannoma. Large retroperitoneal schwannomas are extremely rare tumours. They usually reach a large size when they arise retroperitoneally, which might raise suspicion for malignancy. Such tumors predominate in women schwannomas are usually solitary, slow growing and non-aggressive neoplasm usually found in head and neck region. Retroperitoneal schwannomas are usually large size are rare and are difficult to diagnose clinically. Nevertheless, the mainstay of management remains surgical removal and alternatively, the radio-therapy may prove to be effective. This case report of a 55 yrs male is based on such a patient in whom the diagnosis was established with great difficulty and intraoperative findings were something we had never encountered before. On examination:A visible lump seen in right iliac and right lumbar fossa, divarication of rectii seen.

Adenomatoid tumors are regarded as distinctive benign mesothelial neoplasms of the paratesticular region, most commonly occurring at the tail of the epididymidis. Because of its rarity, the clinical and histopathological aspects are discussed. We present the case of 40 years old male patient came to our OPD with complaints of left hemiscrotal swelling since 6 months duration. A clinical diagnosis of testicular neoplasm was made, but the final diagnosis of adenomatoid tumor was made after excision. Due to its low incidence in intrascrotal pathology, we believe it is important for the physician to be aware of this interesting entity in order to make a differential diagnosis from other inflammatory processes and to adopt the proper surgical approach.

Epitheloid sarcoma is a rare soft tissue sarcoma classified under tumor of uncertain histogenesis. Incidence being 0.4/million/year, it is divided into proximal variant-where in the proximal parts of the body are more involved and distal variant which is commoner and less aggressive of the two predominantly involving distal parts of upper limb followed by distal lower extremities and proximal upper limb. It has a male preponderance (1.8:1), although females have better prognosis comparatively, also it has a tendency of lymphatic spread with 13% metastasis. Recurrence of 77% is reported. Definitive diagnosis is made only on tissue biopsy. Most common variant is pseudo granulomatous type. This case report is based on a case which presented with a single right anterior shoulder swelling and was found to be of epitheloid sarcoma on biopsy. A 60 years old female patient came to OPD of D. Y. Patil Medical College, Pune, with complaints of swelling over her right shoulder since 1 month, initially small and gradually increasing in size of swelling. No history of pain and loss of appetite or weight. On examination, a 4 3 cms firm to hard swelling present over anterior part of right shoulder. It was observed to be non-tender, well defined and mobile. Patient has been investigated with x-ray, FNAC, and ultrasound of the swelling. FNAC was significant other giant cell lesion of soft tissue hence taken up for excision biopsy which showed epitheloid sarcoma on histopathology with faint focal positivity for pancytokeratin and EMA and negative for LCA, CK-3 and S-100.
