Aim: Showcase a clinical case that debuted as a rib plasmacytoma, and that ended up presenting as Multiple Myeloma. Materials and Method: Records of a patient with resection of chest wall tumor. Results: Male patient of 58 years, with one year of costal pain, associated with an indurated increase in volume at the level of the eighth right rib in the mid-axillary line. Chest CT scan demonstrated a suggestive image of plasmacytoma of 79 x 44 mm. Surgical resection was performed, with prolene mesh installation in the defect. Biopsy showed neoplastic compromise due to monoclonal lesion of plasma cells. Study is complemented with bone marrow biopsy confirming multiple myeloma. The patient was treated with adjuvant chemotherapy. Conclusions: Solitary bone plasmacytoma is a low frequency entity, which is associated with the presence of multiple myeloma. At the moment of suspicion, it is necessary to rule out their presence, in order to improve the patient's prognosis.

It is self-limited and the treatment is the surgical excision of the lesion. case report: We report a 69 years old woman consulting for a palpable right breast nodule with a mammography and mammary ultrasound informed as BIRADS 4 and 5, respectively. A core biopsy was informed as a mammary Rosai Dorfman disease. Two years later, due to a lesion growth, the patient was subjected to a partial mastectomy. The pathological study of the surgical piece confirmed the diagnosis of the core biopsy. This disease may resemble a malignant disease and the clue for its diagnosis is the pathological study

Hamartoma and nodular pseudoangiomatous stromal hyperplasia. Differential diagnosis Introduction:... more Hamartoma and nodular pseudoangiomatous stromal hyperplasia. Differential diagnosis Introduction: Hamartoma and nodular pseudoangiomatous stromal hyperplasia (PASH) are inusual breast tumor entities, however, can simulate breast cancer. The only accurate tool is preoperative biopsy. Surgical treatment is curative with low recurrence rate. Objective: To present a case of mammary hamartoma associated with PASH whose initial presentation was suggestive of probable malignancy. Case Report: Woman, 44 years old, admitted to controls because of probable malignant breast disease, mammography was reported as BIRADS 0, breast ultrasound as BIRADS U.S: 5, CORE biopsy reported PASH. Partial mastectomy was performed. On delayed biopsy mammary hamartoma with extensive stromal hyperplasia pseudoangiomatosa was diagnosed. Discussion: PASH and hamartomas are diseases with no specific clinical presentation, radiological findings may be pathognomonic of hamartoma, while not in PASH. In the reported case the pathological study showed an association of these conditions, described in a 16% to 71% breast hamartoma cases. The analysis of the entire surgical specimen is essential for a definitive diagnosis.
