肺原发性炎性肌纤维母细胞瘤1例及文献复习

炎性肌纤维母细胞瘤(inflammatory myofibroblastic tumor,IMT)是一种罕见的主要由纤维母细胞/肌纤维母细胞构成的中间型软组织肿瘤[1]。2002年世界卫生组织(World Health Organization,WHO)将IMT定义为由分化的肌纤维母细胞性梭形细胞组成的,常伴大量浆细胞和(或)淋巴细胞的一种肿瘤。IMT发病年龄跨度较大,几乎在任何年龄都可能发生,但主要发生于儿童和青少年,平均发病年龄为10岁左右,且女性略多见[2]。其组织学形态多种多样,生物学行为总体上表现为交界性或低度恶性,部分病例出现复发,极少数发生转移。本文报道1例确诊为IMT的病例,通过分析病理学特征、免疫组织化学表型、分子检测,并结合临床病理特征、诊断及预后,以期提高对IMT的认识水平。

Childhood bronchial mucoepidermoid tumors: a case report and review of the literature.

A bronchial mucoepidermoid tumor in a 13-year-old female was studied by light and electron microscopy. This is the seventh reported case of this rare bronchial neoplasm in a person less than 16 years of age and the only case, in any age group, which has been studied ultrastructurally. All reported cases of bronchial mucoepidermoid tumors in childhood have been histologically of the low grade (well differentiated) variety with a benign clinical course. Although there are histological features which distinguish this lesion from the even rarer bronchial mucous gland adenoma, the clinical features and biological potential of the two lesions in this age group appear to be identical. The optimal surgical therapy for bronchial mucoepidermoid tumors and mucous gland adenomas, when occurring in children, is identical. There must be total removal of either lesion with the sacrifice of as little normal lung as possible. When technically possible, a sleeve resection of the involved bronchus is recommended; however, in most cases, the location of the lesion requires a lobectomy for complete removal.     

Pancreatic alpha cell tumors: case report and review of the literature

Twenty-eight cases of alpha cell tumors of the pancreatic islets have been reported. The clinical features include typical skin rash (termed migratory necrolytic erythema) and stomatitis with anemia, abnormal glucose tolerance, and weight loss. The time course of the disease is variable but the clinical syndrome may be present for up to 15 years (median five years) before discovery of the tumor. In 3 patients, cure was achieved by surgical resection, and in 17 patients in whom metastatic sites were evaluable, 16 involved the liver. Six patients have received chemotherapy: 4 with streptozotocin (STZ); 1 with dimethyl triazeno imidazole carboxamide (DTIC); and 2 with 5-fluorouracil. All 4 patients receiving STZ responded to therapy with objective regression of the tumor and in 3 the dermatitis syndrome receded as well. The selectivity of the STZ for beta cells observed in animals is contrasted with the specific antitumor activity of STZ for alpha as well as beta and delta cell tumors in man.     

Plasma cell tumors in HIV-positive patients: report of a case and review of the literature

Plasma cell tumors show an increased incidence in HIV-positive patients. The cases reported in the literature suggest that plasma cell tumors occur in a younger age group than that encountered in the general population. Pathologically, many of these tumors show a plasmablastic morphology. Plasma cell tumors in HIV-positive patients may present at unusual sites and progress rapidly to involve multiple sites, including the soft tissues and viscera. The prognosis is generally poor. These features may be related to a combination of factors, including immunodeficiency, oncogenic viruses, and altered cytokine milieu in these patients. A case of plasma cell tumor in an HIV-positive patient is presented.

Kimura's disease: a case report and literature review

Kimura's disease, which occurs endemically in the Far East and sporadically in the West, has so far eluded efforts to determine its exact pathogenesis. It presents as solitary or multiple benign swellings of the skin, has a predilection for the periauricular and scalp regions, and often is associated with regional lymphadenopathy. Morphologically, the lesions are characterized by proliferating blood vessels with rich eosinophilic infiltrate. Peripheral blood eosinophilia and raised serum IgE levels are signature features of the condition. The overall prognosis is good. When surgery is not possible, conservative treatment with either corticosteroids or radiation often can produce a favorable response. Complete surgical excision whenever feasible is the preferred treatment despite a high recurrence rate. Based on a recent case of Kimura's disease in a 55-year-old black woman, we discuss the pitfalls in the diagnosis of this chronic inflammatory disorder.     

Prostate angiosarcoma: a case report and literature review

Angiosarcomas are a relatively rare histological subtype of sarcomas and represent <1% of all sarcomas. Prostate angiosarcoma is extremely rare and displays remarkable clinical and pathological heterogeneity. Despite the rarity, it usually presents with dysuria, hematuria, or pelvic pain and represents a treatment challenge. Only nine cases have been reported in the literature, and we report the 10th case of prostate angiosarcoma and the first case of prostate angiosarcoma with recurrent adenocarcinoma.
