Anaplastic large cell lymphoma presenting as a mass in the uterine cervix: a case report.

T-cell lymphoma is an extremely rare form of malignancy in the female genital tract. Most of the reported cases of lymphoma are B-cell lymphomas. A few cases of primary T-cell lymphomas involving the vagina or the vulva have been reported. We are reporting the first case of anaplastic large cell lymphoma (ALCL) presenting as a uterine cervical mass. The patient is a 24-year-old female who presented to the emergency room with a history of menorrhagia, night sweats and 40-pound weight loss. The diagnosis of ALCL was confirmed through immunohistochemical studies with strong CD30 and ALK expression. Fluorescent hybridization showed a rearrangement of the anaplastic lymphoma kinase (ALK) gene. Since ALCL may have a variable expression of T-cell antigens, the diagnosis may easily be missed when CD45 and/or CD3 is negative, and screening epithelial stains for carcinoma (e.g., p63 and EMA) are positive. CD30 must be performed to raise the consideration of ALCL when reniform nuclei are observed.

Thoracic SMARCA4-Deficient Undifferentiated Tumors With Unusual Presentations: A Case Series.

CONTEXT: Thoracic SMARCA4-deficient undifferentiated tumor (SMARCA4-UT) is a recently described aggressive neoplasm of young smokers defined by SMARCA4 inactivating mutations and characterized by cells with rhabdoid morphology, high mitotic activity, and abundant necrosis. OBJECTIVE: Describe and compare 3 unusual presentations of SMARCA4-UT in older adults, including one presenting as a metastatic lesion mimicking a primary bone sarcoma. Discuss the molecular characteristics of SMARCA4-UT and their relationship to nonsmall-cell lung carcinomas with SMARCA4. DESIGN: Three patients with SMARCA4-UTs were identified utilizing a natural language search in CoPath. hematoxylin and eosin sections from all patients as well as Papanicolaou-stained slides and Diff-Quik-stained slides for the first patient were examined. A broad range of immunostains, including BRG1/SMARCA4, were evaluated. Molecular testing was performed via next-generation sequencing. RESULTS: The 3 patients were aged 58, 70, and 70 years. All had a significant smoking history. The first patient presented with an iliac bone mass and mediastinal lymphadenopathy, the second with mediastinal adenopathy, and the third with a paratracheal mass. All 3 tumors showed a diffuse proliferation of pleomorphic, rhabdoid cells with high mitotic activity and tumor necrosis. SMARCA4 was lost in all 3 tumors by immunohistochemistry. Molecular testing revealed SMARCA4 alterations in the first 2. CONCLUSIONS: Thoracic SMARCA4-UT should be considered in the differential diagnosis of pleomorphic rhabdoid tumors in older adults with a smoking history. Although most present as lung and/or mediastinal masses, they may occasionally present as a metastasis and mimic an undifferentiated sarcoma, representing a potential diagnostic pitfall.

Delirium and correlates of delirium among newly admitted elderly patients: a cross-sectional study in a Saudi general hospital.

BACKGROUND: Delirium is a common, often undiagnosed disorder in elderly patients, but no studies have been conducted in Saudi Arabia. OBJECTIVES: To determine the prevalence of delirium among elderly patients on admission and to identify associated factors. DESIGN: A cross-sectional study. SETTING: Tertiary care hospital, Saudi Arabia. PATIENTS AND METHODS: Elderly patients were evaluated for delirium within 24 hours of admission using the Confusion Assessment Method (CAM). The medical records were also reviewed to identify associated factors and whether the diagnosis of delirium was documented by the admitting physician. MAIN OUTCOME MEASURES: Prevalence of delirium. RESULTS: Of 147 patients aged 60 or over screened for delirium within 24 hours of admission, 32 (21.8%) patients were identified with delirium. Seven (21.9%) of the 32 patients with delirium had documentation of their diagnosis in the patient chart by the attending physician. Univariate logistic regression identified greater age (OR=2.70, 95%-CI: 1.21-6.02), higher unemployment rate (OR=3.30, 95%-CI: 1.43-7.61), more often had 3-5 co-morbidities (OR=2.69, 95%-CI: 1.14-6.33), and more cognitive impairment (OR=38.90, 95%-CI: 8.78-172.34) as risk factors for delirium on admission. Multivariate logistic regression analysis identified greater age (OR=2.53, 95%-CI: 1.08-5.88), higher unemployment rate (OR=3.73, 95%-CI: 1.52-9.13) and 3-5 co-morbidities (OR=3.31, 95%-CI: 1.30-8.46) as risk factors for delirium. CONCLUSIONS: Delirium was common and frequently not recognized in elderly patients admitted to the hospital. Administration of the CAM was very helpful in identifying delirium at admission. LIMITATIONS: The main limitation of our study was the relatively small number of patients which might have limited the power to detect some associations.
