Heterotopic cervical salivary gland tissue was found in a 4-yr-old girl with branchial and otologic abnormalities. Her mother and sister also had heterotopic cervical salivary tissue in association with anomalies that suggest the branchio-otorenal (BOR) syndrome. Heterotopic cervical salivary gland tissue may result from abnormal branchial development. 相似文献

The purpose of this study was to compare the histological characteristics of an autogenous fascia lata graft alone and a fascia
lata graft combined with a deltoid flap in the reconstruction of rotator cuff tears. Ten New Zealand white rabbits were divided
into two groups. Infraspinatus tendon defects (1 × 1 cm) were created in each animal. Reconstruction consisted of either a
fascia lata graft alone or a fascia lata graft combined with a distally based deltoid flap. At 3 months, tissue harvest and
histological analysis was performed. Compared to the fascia lata graft alone, there was significantly increased remodeling
activity and neovascularization in the group that included a deltoid flap. Also, there was pronounced interdigitation at the
graft/flap interface in the latter group. A mutually beneficial relationship may exist when an autogenous fascial graft is
combined with a functional deltoid flap for reconstructing large rotator cuff defects. 相似文献

Sinonasal hemangiopericytoma. A reassessment with electron microscopy, immunohistochemistry, and long-term follow-up 总被引:2,自引:0,他引:2
J H Eichhorn G R Dickersin A K Bhan M L Goodman 《The American journal of surgical pathology》1990,14(9):856-866
Sinonasal hemangiopericytomas are rare, occasionally misdiagnosed neoplasms that have often been considered distinct from hemangiopericytomas of other sites. Eleven cases were studied. Nine arose from the nasal cavity and two from the paranasal sinuses. The patients' mean age was 58 years. In nine cases there were no appreciable mitoses; in two, mitoses were frequent. Of 10 cases studied by immunostaining, all were positive for vimentin; two had faint focal staining for actin; one focally expressed S-100 protein; all were negative for cytokeratins, desmin, and Factor VIII-related antigen; and none bound Ulex europaeus agglutinin 1. Five cases were studied by electron microscopy. The most consistent features were basal lamina-like material partly surrounding tumor cells and completely separating them from endothelium, tapered cytoplasmic extensions, and orderly bundles of filaments. Intercellular junctions and pinocytotic vesicles were present in some tumors. Of nine cases with adequate follow-up, tumors recurred in four cases (44%) after a mean of 6.5 years, and none metastasized. A review of the literature showed that high local recurrence rates, late recurrences, and low rates of metastasis were features of tumors in this location. This might be a reflection of early presentation, small tumor bulk, and difficulty of complete resection, rather than evidence for a biologically distinct neoplasm. 相似文献

Alcohollike liver disease in nonalcoholics. A clinical and histologic comparison with alcohol-induced liver injury 总被引:29,自引:0,他引:29
Individuals who deny alcohol consumption may develop liver injury that histologically resembles the liver injury found in alcoholic patients. To determine whether any clinical or histologic features distinguish alcoholic and nonalcoholic subjects with "alcohollike" liver injury, the clinical records and liver biopsy specimens of 68 alcoholic and 39 nonalcoholic patients with alcohollike injury on liver biopsy were compared. The clinical and biochemical features of the two groups differed significantly. Alcoholism was associated with more severe clinical and biochemical manifestations of liver disease. However, there was considerable overlap among histologic features of the two clinically defined groups. Based on histology alone, alcoholic and nonalcoholic patients were often indistinguishable. The observations suggest that the clinical differences between the alcoholic and non-alcoholic patients cannot be attributed to qualitative or quantitative differences in liver histology. On the other hand, histologic similarities between the two groups raise the possibility that a shared condition, perhaps nutritional or hormonal, is responsible for the histologic expression of alcohollike injury in both groups. 相似文献
