RESUMEN

BACKGROUND Amyloidosis results in fibrillar sheets of beta-pleated amorphous congophilic protein deposition in the extracellular space. Breast amyloidosis is a rare entity, with the first case reported in 1973 and only 2 major case series published since. These deposits can have local or systemic manifestations and typically present unilaterally, although bilateral involvement has been described. Some reported cases of amyloidosis have been linked to breast cancer. CASE REPORT The patient was a 60-year-old woman who presented to the breast surgery clinic for evaluation after image-guided biopsy of a right breast lesion. Core needle biopsy under stereotactic guidance demonstrated pathology consistent with nodular deposition of amyloid, associated with calcifications. Microscopic examination revealed extracellular deposition of acellular eosinophilic material in fat, stoma, and blood vessels. Congo red special stain was positive. Amyloid with Congo red special stain showed apple green birefringence under polarized light. Surgical excision under needle localization was performed, with the final surgical pathology report confirming amyloid deposits. CONCLUSIONS Breast amyloidosis can have calcium affinity, create a foreign body-like reaction with giant cell infiltration, and distribute through periductal, perivascular, or intralobar patterns. Some factors that can contribute to an increased risk or are associated with breast amyloidosis are predisposing clinical conditions, including autoimmune disease, various breast cancers, and B-cell lymphomas. Amyloidosis of the breast should be treated either as primary or secondary, based on etiology. Further studies need to be conducted on whether there are specific genetic markers that predispose populations to the development of amyloidosis of the breast.

RESUMEN

BACKGROUND Hypersplenism, the rapid and premature destruction of blood cells, encompasses a triad of splenomegaly, cytopenias (anemia, leukopenia, or thrombocytopenia), and compensatory bone marrow proliferation. Secondary hypersplenism results from non-intrinsic splenic diseases, such as hemoglobinopathies. Sickle cell disease consists of a group of genotypes, where hemoglobin sickle C disease (HbSC) is the inheritance of hemoglobin S with hemoglobin C. Most homozygous genotypes undergo complete auto-splenectomy by age 6 years, whereas those with HbSC disease rarely do. We report a rare case of hypersplenism and massive splenomegaly in an adult with sickle cell disease, the HbSC genotype, requiring splenectomy. CASE REPORT A 41-year-old woman with known splenomegaly initially presented to the general surgery clinic for management of abdominal pain. She was found to have anemia, indicating cytopenia likely from hypersplenism. Consequently, she underwent splenic artery embolization, followed by an exploratory laparotomy and splenectomy, with an unremarkable postoperative course. CONCLUSIONS Acute splenic sequestration crisis can result from hypersplenism, a potentially fatal complication of sickle hemoglobinemia. The continuous cycle of sickled cell entrapment and stasis causes numerous splenic infarctions, forming splenic parenchymal scar tissue which reduces the spleen's size and functionality - the process of auto-splenectomy. Adults rarely experience these crises past adolescence, which are secondary to the scarring and atrophy from premature auto-splenectomy. Our patient's spleen measured 21.1 cm, larger than the average adult's spleen. In our case, adjunctive preoperative splenic artery embolization likely contributed to decreased intraoperative blood loss during splenectomy, mitigating the need for perioperative transfusions.

RESUMEN

We report a case of right-sided leiomyosarcoma of the kidney with concomitant poorly differentiated squamous cell carcinoma of the cervix diagnosed one month after radical nephrectomy in a previously healthy female patient. This is the first reported case of concomitant leiomyosarcoma of the kidney and squamous cell carcinoma of the cervix, and the diagnosis, clinical presentation, prognosis, and treatment are discussed.
