04/01/2007 - "The concentric structures of myoid cells in angioleiomyomas were, however, consistently negative for desmin. "
04/01/2007 - "Desmin was diffusely positive in 75.7% of solid-type angioleiomyomas, 51.4% of venous type, and 18% of cavernous type, whereas most of the myopericytomas were negative for desmin, even though desmin-positive cells were only partially seen in 3 myopericytomas. "
07/01/2014 - "The histological features and immunohistochemical profile, characterized by positive expression of the spindle-shaped tumor cells for desmin and smooth muscle actin and by positive expression of the endothelial cells of the vascular channels for pan-endothelial markers CD34 and CD31, confirmed the diagnosis of a cavernous-type angioleiomyoma. "
11/01/2003 - "5/5 (100%) arrector pili hamartomas, 10/12 (83%) piloleiomyomas, 4/5 (80%) piloleiomyosarcomas, 1/1 (100%) angioleiomyoma, and 1/7 (14%) angioleiomyosarcomas were positive for desmin. "
01/01/2006 - "Despite overlapping morphologic features to angioleiomyoma and myofibroma, myopericytoma represents a distinct perivascular, myoid neoplasm of skin and soft tissues, characterized by a broad morphologic spectrum of concentrically, perivascularly growing myoid tumor cells that stain positively for ASMA and often for h-caldesmon, whereas desmin is usually negative. "

10/01/2010 - "Of 23 masses, there were 5 giant cell tumors of the tendon sheath, 4 schwannomas, 3 vascular leiomyomas, 2 benign fibrous histiocytomas, 2 dermatofibrosarcoma protuberans, 2 granular cell tumors, 1 dermatofibroma, 1 fibroma of the tendon sheath, 1 fibromatosis, 1 eccrine spiradenoma, and 1 granulation tissue. "
08/01/2011 - "The differential diagnosis of this entity should consider other spindle cell neoplasm, including hemangiopericytoma/solitary fibrous tumor, dermatofibrosarcoma protuberans, myopericytoma, angioleiomyoma, amelanotic melanoma, pecoma, and benign and malignant peripheral nerve tumors. "
07/01/2004 - "In contrast all the following cases were completely unreactive: (i) epithelial tumours (seborrhoeic keratosis, squamous cell carcinoma, Bowen's disease, actinic keratosis, genital Paget's disease); (ii) follicular tumours (basal cell carcinoma, trichilemmoma, trichoepithelioma, trichoblastoma, keratoacanthoma, proliferating trichilemmal tumour, pilomatricoma); (iii) melanocytic tumours (malignant melanoma, naevus cell naevus, Spitz naevus, blue naevus); (iv) neural tumours (schwannoma, neurofibroma, Merkel cell neoplasm); (v) mesenchymal tumours (soft fibroma, dermatofibroma, dermatofibrosarcoma protuberans, vascular leiomyoma, leiomyosarcoma, lipoma, juvenile xanthogranuloma, angiomyoma); and (vi) other sweat gland tumours (poroid neoplasms, syringoma, cylindroma, clear cell hidradenoma, spiradenoma, syringoid eccrine carcinoma, mucinous carcinoma, apocrine cystadenoma, syringocystadenoma papilliferum, apocrine adenocarcinoma). "

03/01/2009 - "Angioleiomyoma is a benign smooth muscle tumor arising from the vessel walls.The"
04/01/1994 - "We further believe that it is most likely of vascular derivation, based on a previous report of angioleiomyoma arising in a dermatofibroma as well as the continuity of fascicles of smooth muscle with a thick-walled vessel in one of our cases. "
10/01/1990 - "The angioleiomyoma may have originated from a vessel in the histiocytoma."

04/01/2007 - "Immunohistochemically, most tumor cells of all cases of both angioleiomyomas and myopericytomas were diffusely positive for actins (alpha-smooth muscle actin and HHF35) and calponin, and all cases, except for 1 myopericytoma, were also diffusely or focally positive for h-caldesmon. "
01/01/2006 - "Despite overlapping morphologic features to angioleiomyoma and myofibroma, myopericytoma represents a distinct perivascular, myoid neoplasm of skin and soft tissues, characterized by a broad morphologic spectrum of concentrically, perivascularly growing myoid tumor cells that stain positively for ASMA and often for h-caldesmon, whereas desmin is usually negative. "

10/01/1995 - "Immunostains for HMB-45 were strongly positive in the uterine LAM in both cases, the retroperitoneal and lymph node lymphangiomyomatous lesions, the uterine angiomyoma, and a resected renal angiomyolipoma. "
09/01/2005 - "Thus, LAM is multisystem disease linked with abdominal tumors (angiomyolipomas, angioleiomyomas). "

07/01/2007 - "From September 2002 to November 2005, there were 22 lung transplantation recipients, suffering from emphysema (10/22), pulmonary fibrosis (10/22), pneumosilicosis (1/22) and vascular leiomyoma (1/22), and all of them were complicated with pulmonary hypertension to different extent. "
01/15/2008 - "Lung transplantation was performed on 30 patients, 12 with chronic obstructive pulmonary disease, 10 with pulmonary fibrosis, 3 with Eisenmenger's syndrome, 3 with bronchiectasis, 1 with pneumosilicosis, and 1 with pulmonary vascular leiomyoma, 24 males and 6 females, aged 48 +/- 13 (15 - 72), 23 undergoing single lung transplantation, 3 undergoing right single lung transplantation following ventricular septal defect repair with CPB, 3 undergoing bilateral sequential lung transplantation without CPB, and 1 case undergoing bilateral sequential lung transplantation with CPB, during the period September 2002 to December 2005. "

10/01/2010 - "Herein, through review of the pertinent oral pathology literature and the detailed description of 2 lesions, one an oral angiomyoma with an adipocytic component and the other an apparently hamartomatous angioleiomyomatous proliferation with adipocytes, we provide, in our opinion, a solid argument against the use of the term AML for non-PEComatous oral tumors."
08/01/2002 - "A retrospective search was performed for angioleiomyomas among all smooth muscle tumors accessioned from 1963 to 2001 in an oral pathology service. "

01/01/2008 - "A smaller, well-circumscribed laryngeal vascular leiomyoma may be easily amenable to transoral laser resection. "

07/01/2006 - "From September 2002 to April 2005, there were 18 cases of lung transplant recipients, who had suffered from emphysema (9 cases), pulmonary fibrosis (5 cases), silicosis (1 cases), bronchiectasis (1 case), pulmonary vascular leiomyoma (1 case), ventricular septal defect and Eisenmenger's syndrome (1 case), respectively.
