Benign cystic mesothelioma of the peritoneum in a male child.

The benign cystic mesothelioma of the peritoneum is a rare lesion that occurs predominatly in women of reproductive age and has a high propensity for local recurrence. It is very rare in childhood, especially in boys, being reported in only 4 cases. A new case of benign cystic mesothelioma of the peritoneum in an 11-year-old boy is reported.

Nerve transfers using collateral branches of the brachial plexus as donors in patients with upper palsy--thirty years' experience.

Background: Nerve transfers in cases of directly irreparable or high-level extensive brachial plexus traction injuries have been done using a variety of donor nerves with various success, but an ideal method has not been established. The purpose of this study is to analyze the results of nerve transfers using the thoracodorsal and medial pectoral nerves as donors in patients with upper palsy.

Methods: This retrospective study included 40 patients with 29 procedures using the thoracodorsal nerve and 33 procedures using the medial pectoral nerve as donors for reinnervation of the musculocutaneous or axillary nerve.

Histological features of gastric cardia in adults: an autopsy study.

Background And Aims: The existence, histology and origin of gastric cardiac mucosa are controversial. The aim of the present study was to determine the existence, histological characteristics and length of cardiac mucosa and to correlate these features with the patients' age and the presence of inflammation in the gastric cardia and/or esophagus. METHODS; The cardiac mucosa within the whole esophagogastric junction was histologically analyzed in 38 consecutive autopsy specimens and measured in 24 cases.

Clear cell myoepithelial carcinoma of the skin. A case report.

Myoepitheliomas are tumors of myoepithelial cells, most frequently diagnosed in the salivary glands. Cutaneous location is very rare, especially for malignant variant. We report a case of recurrent cutaneous myoepithelial carcinoma of the femoral region in a 51-year-old woman.

Intestinal intussusception due to a pyogenic granuloma.

Pyogenic granuloma (PG), also known as lobular capillary hemangioma, is a benign vascular tumor, most commonly arising on the skin and the oral mucosa. Gastrointestinal localization of PG, except for the oral cavity, is exceptionally rare. We describe a case of ileal PG occurring in a 13-year-old girl, presenting with intestinal obstruction.

Intramuscular hemangioma of the retropharyngeal space.

Background: Intramuscular hemangioma (IMH) is a distinctive type of hemangioma occurring within skeletal muscle. Most IMH are located in the lower extremity, particularly in the muscles of the thigh. When present in the head and neck region, the masseter and trapezius muscle are the most frequently involved sites.

Soft tissue myoepithelial carcinoma.

Background: Myoepitheliomas are tumors composed predominantly or exclusively of myoepithelial cells, usually arising in salivary glands. Cutaneous/soft tissue localization is very rare, especially for the malignant myoepitheliomas.

Case Report: We presented a case of myoepithelial carcinoma involving subcutaneous adipose tissue of the left forearm in a woman aged 62 years.

A well-differentiated liposarcoma co-existent with leiomyoma.

Background: The coexistence of a well-differentiated liposarcoma (atypical lipomatous tumor) and benign smooth muscle component in a single soft tissue neoplasm is extremely rare.

Case Report: Histologic and immunohistochemical characteristics of tumor, which represented the recurrence of a retroperitoneal atypical lipoma in a 50-year-old female patient are presented in this paper. The tumor represented the recurrence of a retroperitoneal atypical lipoma.

[Nerve transfer in traction injuries of the brachial plexus].

Background: The aim of this study was to analyze the results of nerve transfer to the musculocutaneous and axillary nerves, using some technical modalities such as intercostal, spinal accessory or intraplexal transfer, and on the basis of the results to try to clarify the most common controversies concerning these operations.

Methods: The study included 82 patients with brachial plexus traction injuries, who were operated on using various techniques of nerve transfer. The follow-up period was at least two years.

Transfer of the medial pectoral nerve: myth or reality?

Objective: Transfer of the medial pectoral nerve is one of the most controversial procedures used to reinnervate the paralyzed upper arm because of brachial plexus spinal nerve root avulsion or directly irreparable proximal lesions of spinal nerves. The purpose of this study was to determine the value of this type of nerve transfer to the musculocutaneous and axillary nerves.

Methods: The 25 patients included in the study comprised 14 patients who had nerve transfer to the musculocutaneous nerve and 11 who underwent nerve transfer to the axillary nerve.
