Primary leiomyosarcoma in testis is an uncommon tumor with few cases reported. It generally develop after radiotherapy or long term taking anabolic steroid medication . We report a 53-year-old male patient with primary testis leiomyosarcoma who presented with painless testicular enlargement without any known predisposing factors. Ultrasound revealed a large heterogeneous left testicular solid lesion. Alpha-fetoprotein (AFP) and beta-human chorionic gonadotrophin (beta-HCG) levels in serum were normal. Left radical orchidectomy following with histology assessment established a diagnosis of primary leiomyosarcoma of testis. No data of cancer metastasis was established. The patient didn’t receive any adjuvant therapy. There wasn’t any evidence of recurrence after 1 year follow-up. Leiomyosarcoma must be one of the differential diagnoses of seronegative tumors in testis. The motivation for this paper is the extreme infrequency of the situation and the differential diagnosis by all expansive inguinoscrotal tumors.

Abstract
Cutaneous leiomyosarcoma is a relatively rare tumor accounts for about 2-3% of superficial soft tissue sarcomas. It occurs more frequently in males in fifth and sixth decades with a predilection for extremities. We report a 27 years old male with cutaneous leiomyosarcoma of thigh, previously diagnosed ...

Cutaneous leiomyosarcoma is a relatively rare tumor accounts for about 2-3% of superficial soft tissue sarcomas. It occurs more frequently in males in fifth and sixth decades with a predilection for extremities. We report a 27 years old male with cutaneous leiomyosarcoma of thigh, previously diagnosed as pleomorphicfibroma. The tumor composed of pleomorphic spindle shaped cells with blunt ended nuclei and high mitotic activity. Smooth muscle actin was positive. In this case, the young age of the patient and previous misdiagnosis of the tumor are interesting. Subtle histologic features of low grade leiomyosarcoma can be a pitfall in diagnosis and so affects the optimal management of the patient as it occurred in previous sample of this case.

Primary sarcomas of the kidney are exceptional. Among renal sarcomas, leiomyosarcoma is the most common histologic subtype amounting to 50-60% of all cases. The tumor usually arises from either the renal capsule or smooth muscle tissue in the renal pelvic wall. In this paper, we report a patient with leiomyosarcoma of the kidney presented with non-specific abdominal pain and a palpable mass. Histologic examination revealed a mesenchymal tumor composed of pleomorphic spindle cells arranged in interlacing pattern with high mitotic activity. Immunohistochemical study was positive for Demin, smooth muscle Actin (SMA), and muscle specific antigen (MSA).The rarity of this disease and very little information about it, its severity, and poor prognosis, uncommon form of presentation, large size of the mass, and difficulty in management are highlighted and reported.

Abstract
Primary leiomyosarcoma of the heart is extremely rare and found in about 0.2% of all cardiac tumors. Here in a 26-year-old man with progressive dyspnea, which had started since 2 months ago, is presented. Echocardiography revealed a left atrial mass, which was suggestive for a atrial myxoma.On the surgery, ...

Primary leiomyosarcoma of the heart is extremely rare and found in about 0.2% of all cardiac tumors. Here in a 26-year-old man with progressive dyspnea, which had started since 2 months ago, is presented. Echocardiography revealed a left atrial mass, which was suggestive for a atrial myxoma.On the surgery, a tumoral tissue in the left atrium and pulmonary veins with attachment to peripheral soft tissue, was seen and incompletely resected. Histologic examination exhibited a hypercellular,necrotic and mitotically active spindle-celled tumor with fascicular arrangement. Immunohistochemistry showed a positive reaction to SMA in tumoral cells. The patient was advised to refer for postoperative chemotherapy, which was rejected. One year later, the patient was brought to hospital with tumor recurrence. Chemotherapy was initiated for the patient immediately, but the patient was expired 3 days later.

Primary leiomyosarcoma of the broad ligament is a very rare, rapidly progressive and highly malignant gynecological tumor and only 16 cases have been reported in the literature. Here, presentation of leiomyosarcoma of the left broad ligament in a 26-years-old woman is reported. Clinical presentation and histological diagnosis is discussed. The patient has been treated surgically and remains disease-free following three years follow up. A review of literature is also performed to discuss the diagnosis and management of leiomyosarcoma of broad ligament.
