Plasma cell granuloma (PCG) is an uncommon benign tumor of unknown etiology, primarily located in the lungs. We report a case of PCG on the gingiva mimicking benign and malignant tumors in a 56-year-old woman. Histopathological examination revealed a relatively sharp circumscribed inflammatory cell infiltration under the mucosa-containing plasma cells, predominantly those including Russell bodies. Plasma cells are stained by CD138 immunohistochemistry. Polyclonal status of the lesion was confirmed by kappa and lambda light chaining. The typical histopathological and immunohistochemical findings in combination with the clinical features were consistent with PCG, about which the literature reports very few cases.
ÖZETLangerhans hücreli histiositoz (LCH) CD-1a boyanması gösteren klonal proliferatif lenfohistiositik bir hastalıktır. Hastalık unifokal veya multifokal tek bir sitemi veya birçok sitemi tutacak şekilde geniş bir klinik seyir gösterebilir. Tutulan alana göre diabetes insipitus, işitme kaybı veya tırnak değişiklikleri oluşabilir. Burada atipik presentasyon gösteren iki vakayı litaretür derlemesi ile beraber sunduk. Anahtar Kelimeler: Langerhans hücreli histiositoz, diabetes insipitus, işitme kaybı, tırnak distrofisi ABSTRACT Langerhans cell histiocytosis (LCH) is a clonal proliferative lymphohistiocytic disorder with mainly CD-1a positive staining. It has a wide spectrum of unifocal or multifocal mono or multisystemic disease. Rare symptoms like diabetes insipidus, hearing loss or nail distrophy might also occur according to the involved sites. In here, two cases of LCH with atypical presentation are reported with review of the literature.
Primary Thyroid lymphoma is an uncommon malignancy, which can rarely cause severe dyspnea. Its commonly difficultly diagnosed and rapid diagnosis and management may be lifesaving. Here we report a case presented with sudden thyroid growth and severe dyspnea, who was diagnosed as primary thyroid lymphoma. A 70-year-old woman applied with fatigue, rapidly enlarged goitre and severe progressive dyspnea. She had severe hypoxemia with an artery oxygen saturation of 59.2% and arterial PO2 of 33.9 mmHg. The ultrasound of the neck showed an enlarged thyroid gland with a mass in the left lobe. After admission to the hospital her dyspnea worsened and oxygen and bronchodilator treatment gave no benefit. IV methylprednisolone was administered, and the patient's symptoms partially improved. Meanwhile in spite of supportive therapy, the patient underwent urgent surgery for acute airway obstruction and thyroidectomy was performed. After surgery the diagnosis was high grade diffuse large B-cell non-Hodgkin's lymphoma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
