“…Primary breast sarcomas are rare tumors originating from the mesenchymal tissue of the breast and usually occur in postmenopausal women [ 1 ]. It is a heterogeneous group that accounts for less than 1% of all primary breast tumors [ 2 , 3 ]. It is even rarer in men; fewer than 10 cases have been reported in men in the literature up to 2018 [ 4 ].…”

Introduction Primary sarcoma in man is very rare and knowledge about this tumor is limited with very few cases published in the literature. Case report A 65-year-old man operated on 20 years ago for a left breast tumor with a skin graft at the tumor site (no documentation or pathology report). He consulted for a mass in the left breast, bleeding on contact, associated with nodules in the right breast that looked suspicious. On breast ultrasound, a tissue formation in the lower medial quadrant of the left breast with irregular contours, measuring 42 × 53mm with the presence of several suspicious tissue formations in the right breast, the largest measuring 2 × 2cm. Surgical removal of the left mass with a right mastectomy with pathology report of breast leiomyosarcoma with healthy surgical borders followed by radiotherapy for local control. Discussion Leiomyosarcoma is an extremely rare tumor in the breast and usually originates from the blood vessels, myoepithelium, or nipple musculature, as in our case. Breast sarcomas represent less than 1% of all malignant neoplasms of the breast. Their incidence in women is much higher than in men. Conclusion Primary breast sarcomas are rare tumors that originate from the mesenchymal tissue of the breast and represent less than 1% of all malignant neoplasms of the breast. Their diagnosis is confirmed by biopsy with immunohistochemical and only surgery can guarantee cure. Radiotherapy is recommended for local control after surgery.

A rare case of primary breast angiosarcoma in a male: a case report

et al. 2018

BackgroundSarcomas account for less than 1% of primary breast cancers, and breast angiosarcomas are responsible for only 0.05% of all breast malignancies. The male breast has the same potential for malignant transformation as the female breast. However, due to anatomical differences in the breast and the low incidence of angiosarcoma, it is difficult to determine how male breasts can be affected by this type of tumor.Case presentationA 36-year-old male patient was admitted to the hospital with a palpable lump in his right breast. Lymphadenopathy was negative. Ultrasonography showed a hypoechoic mass with partially defined contours, measuring 4.0 × 3.0 cm, with muscle infiltration. Histological examination revealed a malignant tumor. Radical mastectomy was then performed with clear surgical margins. The patient began chemotherapy with paclitaxel. Following the second cycle of chemotherapy, he presented with headache and seizures due to a frontal lobe metastasis. Twenty days after the onset of neurological symptoms, the patient died.ConclusionsPrimary angiosarcomas of the male breast are extremely rare. This is the sixth case published in the literature. It is in agreement with other studies in the literature concerning clinical presentation and poor prognosis. Treatment consists in surgical removal of the tumor with clear margins and without axillary lymphadenectomy.

Leiomyosarcoma of the Inferior Vena Cava with Hepatic and Pulmonary Metastases: Case Report

et al. 2019

Sarcomas are connective tissue tumors accounting for only 1% of all adult malignancies. Leiomyosarcoma (LMS) is a sarcoma arising from smooth muscle cells, and accounts for 10-20% of all sarcomas. A subtype of LMS are those originating from the smooth muscle of blood vessels. Leiomyosarcoma of the inferior vena cava is a sarcomatous tumor, with less than 350 cases described in the literature. It carries a poor prognosis, with 5- and 10-year survival rates of 31.4% and 7.4%, respectively. We present a case of a 46-year-old female with no significant past medical history presented to the emergency department with mild abdominal pain and distention, early satiety, and weight loss for three weeks, found to have unresectable metastatic leiomyosarcoma of the inferior vena cava.
