Primary Cutaneous Malignant Perivascular Epithelioïd Cell Tumor (PEComa): Case Report With Review of the Literature.

Perivascular epithelioïd cell tumor (PEComa) is a mesenchymal neoplasm with epithelioïd or spindled morphology with numerous thin-walled capillaries between tumor cells. They co-express markers of both melanocytic and smooth muscle differentiation. PEComas are rare, presenting in numerous anatomic sites including lung, kidney, liver, genitourinary tract, soft tissue, and skin.

Aseptic nonunion of the tibia treated by plating and bone grafting: retrospective study about 40 cases.

Objective: The objective of this study was to evaluate the clinical and radiological results of the treatment of aseptic nonunion of the tibia by plating and bone grafting.

Material And Methods: This retrospective study included 40 patients with aseptic nonunion of the tibia, treated in the Trauma-Orthopedic department B4 of CHU Hassan II in Fez-Morocco. The average age was 41 years (range 25-60 years).

[Coverage in the management of loss of skin substances on the lower third of the leg: about 9 cases].

Coverage of loss of skin substances on the lower third of the leg is a challenging problem. This is due to adjacent soft tissues impairment, shortage of local vascularization and bone exposure. We conducted a retrospective study of a series of 9 cases of skin coverage of the lower third of the leg treated at the University Hospital Hassan II of Fez from 2016 to 2018.

[Glomus tumors of the hand: a retrospective study of 11 cases].

MASSON described glomus tumour as a benign neuromyoarterial proliferation. It represents approximately 1% -5% of all tumors of the hand. Pain is the main clinical sign.

Hoffa's fat pad tumours like: results of the arthroscopic resection.

We performed a retrospective cohort study to increase awareness in orthopaedic community of this rare but interesting disease which is often misdiagnosed as meniscal pathology and to analyze present results of arthroscopic resection in seven patients. we retrospectively reviewed records from 2008-2012 and identified 7 patients with symptomatic Hoffa's fat pad impingement. The diagnosis was made by clinical exam, MRI imaging and verified arthroscopically.

An unusual cause of shoulder pain in an elderly woman: a case report.

Introduction: Stress fracture of the clavicle is a rare entity. It can manifest itself with an atypical shoulder pain. The clavicle is vulnerable to pathological fractures from several causes such as neoplasm, infection and rarely metabolic bone disease.

Functional outcome of midclavicular fracture fixation utilising a reconstruction plate.

Background: Clavicular fractures are common injuries. The aim of this study is to present results of surgical treatment of midclavicular fracture managed with open reduction and internal fixation (ORIF) with superior reconstruction plating. This study involved 34 patients, with mean age of 31 years, with completely displaced midclavicular fractures, 28 on the right and 6 on the left, stabilized by contoured plate.

DC-SIGN, but not sDC-SIGN, can modulate IL-2 production from PMA- and anti-CD3-stimulated primary human CD4 T cells.

Dendritic cell (DC)-specific intercellular cell adhesion molecule-3 (ICAM-3)-grabbing non-integrin (DC-SIGN) is expressed on the surface of DCs and specialized macrophages and can support T cell proliferation. Antibody-mediated co-ligation of CD3 and ICAM-3, the ligand for both DC-SIGN and leukocyte function-associated antigen-1, leads to T cell activation. Therefore, we tested to see whether DC-SIGN or a splice variant of dendritic cell-specific intercellular cell adhesion molecule-3-grabbing non-integrin (sDC-SIGN) can co-stimulate primary human T cells.
