Uterine angiomyolipoma associated with pregnancy.

Uterine angiomyolipomas are rare lesions composed of mature adipose tissue, smooth muscle, fibrous connective tissue, and blood vessels in varying proportions. We reported the first case of angiomyolipoma associated with a normal pregnancy. Initially, the tumor developed intramurally and could have been confused with a partial molar gestation.

[The place of composite flaps in maxillofacial surgery].

The preferred composite flap is the musculocutaneous flap from pectoralis major for repair of loss of mucocutaneous substance due to cancer or injury. In rare indications the musculocutaneous flap from sternocleidomastoid muscle is used. When loss of bone substance combined with a cutaneous or mucosal defect has to be corrected use is made of the bone-muscle-skin flap from pectoralis major to include the 5th rib, or the bone-muscle-skin flap from sternocleidomastoid to include internal portion of clavicle.

Melanotic neurofibroma: a case report with ultrastructural study.

The authors report a case of a solitary melanotic neurofibroma involving the temporomalar area in a 17-year-old man. Light-microscopic study reveals a benign neurofibroma including melanin deposits. Electron microscopy shows typical premelanosomes and melanosomes within Schwann cell cytoplasm.

[Current treatment of osteoradionecrosis].

Conventional treatment of osteoradionecrosis of mandible is by antibiotics combined if necessary with a hemimandibulectomy. A method is proposed which reduces bone excision to infected and necrotic tissue while respecting mandibular continuity. The bone remaining is covered by a flap taken from a distant region.

Localization of lactoferrin and nonspecific cross-reacting antigen in human breast carcinomas. An immunohistochemical study using the avidin-biotin-peroxidase complex method.

A retrospective immunocytochemical study was performed on 67 human breast carcinomas to determine whether the epithelial cell-associated antigens, lactoferrin and nonspecific cross-reacting antigen (NCA), could be used as markers in the prognostic assessment of breast cancers. Fixed paraffin sections were tested with anti-lactoferrin and anti-NCA. Lactoferrin and NCA were found in 7.
