Hemangiopericytoma/solitary fibrous tumor of pectoralis major muscle mimicking a breast mass.

Introduction: Hemangiopericytoma (HPC)/solitary fibrous tumor (SFT) is a very uncommon tumor of uncertain malignant behavior. In 1942, Stout and Murray first characterized these neoplasms as "vascular tumors arising from Zimmerman's pericytes" and till now hemangiopericytomas and solitary fibrous tumors of the soft tissues are regarded as features of the same entity in the soft tissue fascicle.

Presentation Of Case: We present a case of hemangiopericytoma/solitary fibrous tumor of the pectoralis major muscle in a 33-year-old female.

Breast tumour as the first manifestation of extramedullary relapse of Philadelphia positive (Ph+) acute lymphoblastic leukemia.

Extramedullary relapses of acute lymphoblastic leukemia (ALL) are rare and usually localized in the central nervous system. We describe such an uncommon case of extramedullary relapse of ALL in the breast of a 44 year old female. The patient, who had been diagnosed with precursor B cell, Philadelphia positive (Ph+) acute lymphoblastic leukemia (ALL) 5 years before and had been in complete molecular remission for the last 19 months, was admitted to the hospital for investigation of a hard, non-tender lump in her right breast.

Axillary silicone lymphadenopathy secondary to augmentation mammaplasty.

We report a case involving a 45-year-old woman, who presented with an axillary mass 10 years after bilateral cosmetic augmentation mammaplasty. A lump was detected in the left axilla, and subsequent mammography and magnetic resonance imaging demonstrated intracapsular rupture of the left breast prosthesis. An excisional biopsy of the left axillary lesion and replacement of the ruptured implant was performed.

Plasmacytoid myoepithelioma of the palate: case report.

Myoepitheliomas are extremely rare benign neoplasms of salivary glands. They represent 1-1.5% of all salivary gland tumors.

Pure mucinous carcinoma with axillary lymph node metastasis in a male breast.

Pure mucinous carcinoma of the male breast is an extremely uncommon malignant breast neoplasm and usually occurs at advanced age. It is characterized by a higher degree of mucus production, a more benign behavior, a lower incidence of metastatic nodal involvement, and a subsequent higher survival rate. We describe such a case of a 59-year-old male, who displayed a gradually growing retroareolar tumor of the right breast.

Solid variant of a pure intracystic papillary carcinoma of the breast: case report.

Intracystic papillary carcinoma (IPC) of the breast is an uncommon malignant breast neoplasm and usually occurs in advanced age. It is characterized by a more benign behavior and a subsequent higher survival rate. We describe such a case of a 58-year-old female, who displayed a gradually growing tumor of the right breast.

Primary osteogenic sarcoma of the breast.

Primary osteogenic sarcomas of the breast are exceptionally uncommon. We describe such a case occurring in a 66-year-old woman who presented with a hard mass in her left breast. Mammography and breast ultrasonography showed a calcified breast lump, but features were not diagnostic.

Pulmonary sarcoidosis simulating metastatic breast cancer.

The clinical appearance and imaging findings of sarcoidosis and breast carcinoma may sometimes mimic one another, making the differential diagnosis between these two diseases difficult in some cases. A 69-year-old woman displayed an irregular shaped lesion in her left breast. Preoperative localization modalities detected a breast mass with malignant characters.

Axillary lymph node metastases as the sole clinical site of occult breast carcinoma.

Patients without evidence of breast disease, who present with axillary lymph node metastases, consistent with breast origin, comprise a diagnostic and therapeutic dilemma. We describe such a case of a 47-year-old female, who complained of swelling and pain of the left axilla, but no breast mass was palpable. Although histology identified a metastatic adenocarcinoma in the lymph nodes, numerous tests failed to detect the primary tumor.

Histopathological findings of the endometrium in patients with dysfunctional uterine bleeding.

The histopathological examination of the endometrium in cases of abnormal functional uterine bleeding frequently reveals the type of functional disturbance and assists correct treatment. On this basis, 7,000 endometrial curettages from patients with abnormal uterine bleeding were studied. The 1,282 cases with no endometrium in phase, organic changes, or systemic disorders were defined as dysfunctional uterine bleeding; the endometrial lesions were then classified and the histological findings correlated with the patients' ages.
