An unusual cause of shoulder pain: osteochondroma of ventral scapula (a case report).

Osteochondromas mainly affect the metaphysis of long bones such as femur, humerus, and tibia. It is unusual in flat bones such as scapula. Osteochondroma of ventral surface of scapula is one of the rare cause of shoulder pain and difficult to diagnose in first place.

OBJECTIVE MULTI-STATION CLINICAL EVALUATION IN PATHOLOGICAL ANATOMY. CRITICAL ANALYSIS AND PERCEPTION.

Background: Multi-station objective clinical evaluation (MSOCE) is an equitable and genuine formative and normative assessment tool that is deemed relevant to its effectiveness, reliability and validity in clinical evaluation. However, no experience with its application in pathological anatomy has been published.

Aim: To carry out a critical analysis and a perceptual study of the MSOCE in pathological anatomy in medical students.

An Immunoscore System Based On CD3 And CD8 Infiltrating Lymphocytes Densities To Predict The Outcome Of Patients With Colorectal Adenocarcinoma.

Purpose: The aim of this study was to evaluate the Immunoscore (IS) methodology as a prognostic marker of colorectal adenocarcinoma in Tunisian population. Tumor blocks were retrospectively collected from 106 patients with sporadic colorectal cancer.

Methods: Immunohistochemical staining and images analysis software were used to quantify the density of CD3 and CD8 tumor-infiltrating lymphocytes in the center of the tumor and invasive margin.

Primary signet-ring cell carcinoma of the urinary bladder: A report of two cases.

Introduction: Primitive bladder adenocarcinomas account for about 2% of urinary bladder tumors. Primary signet-ring cell carcinoma is a rare variant of bladder adenocarcinoma. It is characterized by a late diagnosis and a poor prognosis.

Accuracy of fine-needle aspiration cytology of head and neck masses.

Background: Head and neck masses are a common presentation in daily practice and can be challenging to both clinicians and cytopathologists. Fine needle aspiration cytology (FNAC) is a widely used method for the diagnosis of head and neck masses. The aim of the study was to assess our institutional experience of the accuracy of FNAC in the diagnosis of head and neck masses.

Prognostic values of detecting MSI phenotypes in colorectal carcinoma by immunohistochemical method compared to molecular investigation.

Background: The identification essentially of hMSH2 and/or hMLH1 alterations has clinical implications for recognition and prognosis of MSI phenotypes cases. In this study, we tried to identify instability by immunohistochemical expression pattern analysis, compared the results with molecular investigation and shown their usefulness as predictive factors for determination of Microsatellite Instability in patients with colorectal carcinomas in routinely.

Methods: Forty seven colorectal cancers and their adjacent colonic mucosa were selected retrospectively for this study.

Giant cell tumor of soft tissues: A case report of extra-articular diffuse-type giant cell tumor of the quadriceps.

Introduction: Giant cell tumors of soft tissue (GCTs) are a relatively rare entity. It is a distinct but uncommon group of neoplasms morphologically identical to osseous giant cell tumor. The diffuse type of extra-articular GCT arising within muscle is a rare benign soft tissue tumor with a wide spectrum of clinical presentation.

[Immunohistochemical analysis of mismatch repair proteins in colorectal adenomas].

Background: The deficiency of mismatch repair system is one of the main pathways in colorectal cancer. This system consists mainly of four proteins: MLH1, MSH2, MSH6 and PMS2. Colorectal cancer develops in the majority of cases from precancerous lesions called adenomas.

Parent-adolescent relationships and social adjustment: the case of a collectivistic culture.

This study examined how parent-adolescent relationships are related to adolescent loneliness, interpersonal difficulties and school adjustment among Israeli Arabs. Two hundred and thirty-one 11th graders (103 boys and 128 girls) and their homeroom teachers participated. Four groups of adolescents were identified according to parenting practice profiles: Adolescents in the harsh parenting group reported the highest levels of loneliness, those in the distant and mixed groups reported midway levels of loneliness, and those in the warm group showed the lowest degree of loneliness and the lowest levels of interpersonal problems.

[An exceptional hepatic tumor].

Background: Hepatic localization of non Hodgkin's lymphoma is generally secondary. Primary localizations are rare.

Aim: To report a rare case of primary hepatic lymphoma particular by its association with dermatopolymyositis.

[Pelvic ganglioneuroma. Report of a case].

Ganglioneuroma is a rare benign tumor. It is the most mature of neurogenic tumors. We report a case of a pelvic ganglioneuroma diagnosed in 24-year-old pregnant woman who presented with an urinary infection.

[Prostatic stromal sarcoma].

Prostatic sarcoma is a very rare tumour arising from the specialized stroma of the prostatic parenchyma. The clinical and histological features and biological behaviour of this entity are poorly elucidated at the present time. The authors report a case of prostatic stromal sarcoma in a 47-year-old man presenting with complete bladder retention.

[Retroperitoneal Castleman disease].

Castleman disease or angiofollicular lymph node hyperplasia is a rare disease of unknown cause with polymorphic clinical features that raises many diagnostic and therapeutic problems. The unifocal, localized, pseudoneoplastic form, first described in 1956, has a good prognosis, but the multifocal form has a more aggressive course. Three histological types have been identified: hyaline vascular, plasma cell and mixed.

[Prognostic value of clinicopathologic factors in superficial bladder tumors: a retrospective analysis].

Objective: To study, through a series of superficial bladder tumors, the prognostic factors of recurrence and tumoral progression.

Materials And Methods: This is a retrospective study of a series of 59 urothelial tumors of the bladder at stage pTa or pT1. The following parameters were considered: age, sex, treatment, stage and grade.

[A particular hepatocellular carcinoma combining the ordinary and the fibrolamellar variant].

Fibrolamellar carcinoma (FLC) of the liver is a rare variant of hepatocellular carcinoma (HCC) occurring on non cirrhotic liver. Since its first description by Hugh Edmondson in 1956, 200 cases of FLC have been reported in the literature, but only some cases describe the association of the ordinary HCC with the FLC within the same lesion. We report in this study the case of a 14-year-old female patient with a hepatic mass whose radiological aspect evoked a nodular and focal hyperplasia.

[Jaccoud arthropathy and pyrophosphate arthropathy: a rare association].

Jaccoud's arthropathy (JA) is a chronic deformity affecting hands and feet, which are voluntarily correctable by the patients. JA was usually reported in association with rheumatic fever and systemic lupus erythematosus. We describe an exceptional association between a pyrophosphate arthropathy and JA of the hands.
