Report of an uncommon complication of acupuncture and wet cupping.A 54-year-old man presented with neck pain and fever. Magnetic resonance imaging of the cervical spine revealed an epidural abscess at C4 to T2.The symptoms related to epidural abscess resolved partially after treatment with antibiotics.Acupuncture and wet-cupping therapy should be taken into consideration as a cause of spinal epidural abscesses in patients who present with neck pain and fever. Furthermore, acupuncture and wet-cupping practitioners should pay attention to hygienic measures.

Cystic lymphangioma of the adrenal gland is a rare and benign lesion, most often found incidentally during abdominal imaging studies, abdominal surgery or at autopsy. We aimed to retrospectively review all adrenal lymphangioma cases at our hospital, further document their lymphatic origin by immunohistochemical staining and discuss the differential diagnosis with other cystic adrenal gland lesions. A total of 3 adrenal lymphangioma cases were identified. All three patients were men and adults at time of diagnosis aged 41 years, 43 years, and 66 years, respectively. All were incidentally identified during investigating for unrelated reasons, two of which were discovered by routine radiologic check-up while the last one was found during imaging detection of ureteral cancer. The average size of an adrenal lymphangioma lesion was 3.2 cm (range, 2.5-4.6 cm). Histologically, all three cases showed a typical multicystic architecture with dilated spaces lined by flattened, bland, simple lining. The cystic spaces occasionally contained proteinaceous material but lacked red blood cell content. On immunohistochemical stains, D2-40 cytoplasmic staining was positive in all three lesions, whereas AE1/AE3 was negative, thus, confirming their lymphatic nature.

Adenomatoid tumors (AT) are uncommon, benign tumors of mesothelial origination most frequently encountered in the genital tracts of both sexes. Their occurrences in the extragenital sites are much rarer and could elicit a variety of differential diagnosis both clinically and morphologically. With regard to the adrenal gland, to the best knowledge of us, only 31 cases of AT have been reported in the English literature. Several histologic growth patterns have been documented in AT, among which cystic type is the least common one. We herein present a further case of AT arising in the adrenal of a 62-year-old Chinese man with a medical history for systemic hypertensive disease. The tumor was incidentally identified during routine medical examination. An abdomen computed tomography scan revealed a solitary mass in the right adrenal. Grossly, the poorly-circumscribed mass measured 3.0 x 3.0 x 2.0 cm with a cut surface showing a gelatinous texture with numerous tiny cystic structures. Microscopic examination showed an infiltrated lesion with honeycomb appearance mimicking a lymphangioma, which composed predominantly of variably sized and shaped anastomosing small cystic spaces lined by flattened endothelial-like cells, without any epithelioid or signet-ring like components present. Foci of extraadrenal tumor extension, lymphoid aggregates with occasional germinal centre formation, intralesional fat tissue, stromal myoid proliferation and ossification were also observed. Immunohistochemical analyses confirmed the mesothelial differentiation of this tumor and indicated a diagnosis of cystic lymphangiomatoid AT of the adrenal.

Long non-coding RNAs are involved in various biological processes and diseases. The biological role of long intergenic non-coding RNA-p21 (lincRNA-p21) in liver fibrosis remains unknown before this study. In this study, we observed marked reduction of lincRNA-p21 expression in mice liver fibrosis models and human cirrhotic liver. Over-expression of lincRNA-p21 suppressed activation of hepatic stellate cells (HSCs) in vitro. Lentivirus-mediated lincRNA-p21 transfer into mice decreased the severity of liver fibrosis in vivo. Additionally, lincRNA-p21 reversed the activation of HSCs to their quiescent phenotype. The mRNA levels of lincRNA-p21 and p21 were positively correlated. Our results show that over-expression of lincRNA-p21 promotes up-regulation of p21 at both the mRNA and protein levels. Furthermore, lincRNA-p21 inhibited cell-cycle progression and proliferation of primary HSCs through enhancement of p21 expression. Compared with healthy subjects, serum lincRNA-p21 levels were significantly lower in patients with liver cirrhosis, especially those with decompensation. These findings collectively indicate that lincRNA-p21 is a mediator of HSC activation, supporting its utility as a novel therapeutic target for liver fibrosis.

Myopericytoma is a benign mesenchymal neoplasm thought to comprise part of a spectrum of perivascular myoid cell neoplasms with myofibroma, angioleiomyoma, and glomus tumor. We describe 2 such neoplasms involving the urinary tract: 1 incidentally identified in the kidney of a 59-year-old woman and 1 in the urinary bladder of a 52-year-old woman who presented with urinary frequency and dysuria. Histologically, the bladder tumor was composed of numerous blood vessels surrounded by plump perivascular myoid cells, as in subcutaneous myopericytoma. The renal tumor showed similar morphology centrally and a symplastic glomus tumor-like growth pattern at the periphery. Immunohistochemically, both tumors were reactive for markers of smooth muscle differentiation, such as smooth muscle actin and caldesmon/calponin but negative for CD34, cathepsin K, and S100 protein. Both patients are free of disease 14 and 39 months after resection, respectively. Our findings broaden the morphologic spectrum of myopericytoma. © 2014 Elsevier Inc.

Anastomosing hemangioma is a recently described, unusual variant of capillary hemangioma which seems to be unique for the genitourinary system, with a particular proclivity for the kidney. Histologically, it is characterized by a unique sinusoidal architecture reminiscent of splenic parenchyma that can lead to concern for angiosarcoma. We herein report a further case of anastomosing hemangioma originating in the right kidney of a 48-yearold Chinese man. The patient had a past medical history significant for hepatocellular carcinoma; this tumor was incidentally identified as an asymptomatic right renal mass during the periodical surveillance of the hepatic cancer. The resected tumor measured 2.5cm in maximum diameter and microscopically demonstrated an overall lobulated growth pattern with alternating cellular areas composed of anastomosing sinusoidal capillary-sized vessels lined by hobnail endothelial cells, and edematous, hyaline paucicellular areas. Cytologically the tumor cells were generally bland and exhibited positivity for CD31, CD34 immunohistochemically. The patient had been in a good status without evidence of tumor recurrence 12 months after the surgery. This rare variant renal hemangioma is in need of more recognition and should not be over-diagnosed as a malignance, particularly angiosarcoma.

Hemangioblastoma is a benign, morphologically distinctive neoplasm of disputed histogenesis that typically occurs in the central nervous system either in the setting of von Hippel-Lindau disease or more often sporadically. Extraneural hemangioblastoma is exceptional and raises a challenging differential diagnosis. Herein, we report a primary renal hemangioblastoma occurring in 51-year-old woman without stigmata of von Hippel-Lindau disease. Histologically, the tumor was composed of sheets of polygonal epithelioid stromal cells with ample pale or eosinophilic, vacuolated cytoplasm in an arborizing capillary network. Tumor cells showed variable nuclear pleomorphism, intranuclear cytoplasmic invaginations, scattered hyaline globules, and psammoma-like calcifications. Some areas showed branching hemangiopericytoma- like vessels with tumor cells radiating from the wall, while other areas were edematous and hyalinized with sparse stromal cells and abundant reticular vessels. Immunohistochemically, the tumor cells reacted strongly and diffusely with antibodies to PAX8, CD10, α-inhibin, S100 protein, neuron-specific enolase, and vimentin, and they showed focal positivity with antibodies to epithelial membrane antigen and AE1/AE3. Tumor cells were negative for CK7, CK8/18, RCC antigen, synaptophysin, chromogranin, c-kit, D2-40, HMB45, melan-A, cathepsin K, SMA, desmin, CD31, CD34, and estrogen and progesterone receptors. Positive immunoreactivity for PAX8 is unexpected and contrasts to central nervous system (CNS) hemangioblastomas, which are essentially always negative for PAX8. This novel finding adds support to the hypothesis that the immunoprofile of extraneural hemangioblastoma varies with site of origin, perhaps as a result of tumor cell lineage and retention of organ-specific markers or acquisition of site-specific antigens due to local factors. © 2013 Elsevier Inc.
