Persistent truncus arteriosus in monozygotic twins: Case report and literature review

We report on a pair of monozygotic twins with persistent truncus arteriosus. They had no evident clinical signs of DiGeorge syndrome. Pathologic examination of the placenta and DNA analysis in chromosomes 7, 8, and 15 was consistent with monozygosity. Fluorescence in situ hybridization test was negative for chromosome 22q11 microdeletion. Family history revealed a female cousin with tetralogy of Fallot. The isolated presence of this conotruncal abnormality in monozygotic twins is extremely rare. The genetic considerations are discussed. Am. J. Med.

Deep femoral artery with four variations: a case report

During our routine dissection course for students we found a complex variation of the femoral artery on the left side of a 72-year-old male cadaver. The deep femoral artery was originating from the anterior aspect of the femoral artery; the inferior epigastric and the external pudendal arteries were arising from the deep femoral artery. Besides, the lateral circumflex femoral artery was arising from the lateral aspect of the femoral artery and distal to the origin of the deep femoral artery.     

Congenital neuroblastoma with multiple metastases: a case report

Neuroblastomas are derived from the neural crest ectoderm, and are the most common solid abdominal masses of infancy. Congenital neuroblastoma, however, is rare. We report a rare case of congenital neuroblastoma with multiple metastases found at autopsy, performed at 2 days after birth. He was born by cesarian section and weighed 2,350 g. His respiration was weak and abdomen was distended. The patient died 2 days after birth. Postmortem examination revealed a relatively well demarcated ovoid mass, in the left adrenal, with necrosis and hemorrhage. Multiple small metastatic tumor nodules in the liver, lung, kidney, brain, rib, thyroid glands, and spleen, were noted. The histopathological pictures confirmed the diagnosis of neuroblastoma of the adrenal with multiple metastasis.

Cardial leiomyosarcoma with multiple lesions involved: a case report

Background: Leiomyosarcoma of the heart is extremely rare and may involve many symptoms. The outcome is poor and the median survival is only 6 months. Case presentation: A 43-years-old female patient complained of palpitation and dyspnea and was diagnosed as bilateral iliac vein-inferior vena cava-right atrium-pulmonary masses. Pathological diagnosis was leiomyosarcoma of vascular origin and she survived for 12 months after surgery. Conclusion: According to the summarization of 30 vascular leiomyosarcoma cases with heart involved we can find that surgical resection is the basic treatment for cardiac leiomyosarcoma, and surgery combined with chemotherapy may be able to further prolong survival.     

An unreported pattern of musculocutaneous and median nerve communication with multiple variations of biceps brachii: a case report

An unreported pattern of communication between musculocutaneous (Mcn) and median nerve (Mn) with multiple variations of biceps brachii (Bb) was observed during the dissection of a male cadaver. The first branch of the Mcn ended in coracobrachialis (Cb). The second was the main Mcn piercing the Cb and giving its motor branches to the muscles of the anterior compartment of the arm. It then continued as the lateral cutaneous nerve of the forearm. The largest third branch also pierced the Cb distal to the main Mcn and communicated with the Mn which was classically formed by relevant roots of the medial and lateral cords. Additionally, a third head of Bb was observed bilaterally. Slips from the pectoralis major were inserted on the tendon of the third head on both sides. The origin of the third head was the greater tubercle to the left and the joint capsule to the right. These extremely rare patterns of both variations which were seen concomitantly in the same subject do not exist in the literature. Lack of awareness of such variations with different patterns of communications between Mcn and Mn might complicate surgical repair of the nerves. Knowing different patterns of Bb variations also have clinical importance as they also may cause compression of neurovascular structures or confuse a surgeon during surgical procedures.     

Sweat gland carcinoma with multiple local recurrences: a case report

We report a case of primary, high grade sweat gland carcinoma, a rare tumor, occurring in the skin of the left axilla. The patient, a 54-year-old man, was treated with wide surgical excision and lymph node dissection; he had developed metastatic deposits in one regional lymph node. The neoplasm relapsed locally thrice in a period of 10 years; however, distant metastases were not found. The differential diagnosis of sweat gland tumors is discussed in the present article.
