It accounts for 20% of carcinomas in men and 10-15% of carcinomas in women. Despite its high incidence, metastatic events are exceedingly rare. The reported frequency of metastatic dissemination is estimated at 0.0028-0.5 percent. Once metastasis is detected, there is a high mortality rate of 50% within 8 months. METHODS: In this study, we present a case of simultaneous lung and parotid metastases of giant BCC primary located on the right medial canthus of a 62 year old female. RESULTS: Examination of the tumor located on the medial canthus obtained showed "adenoid BCC". Computed tomography (CT) was performed to evaluate parotid region for evaluation of parotid gland and chest. Parotid and lung metastasis were detected in CT. Routine labarotory tests and radiological investigations were done. There was no abnormal finding. We also investigated this patient with a bone scan (normal), abdominal an...

METHODS: Two acquired clitoromegaly cases treated in Ataturk Training Hospital, Izmir, Turkey are presented. RESULTS: History from both patients revealed clitoromegaly over the last three years. Neither gynecological nor systemic abnormalities were detected in either patient. Karyotype analyses and hormonal tests were normal. Abdominal and gynaecological ultrasound did not show any cystic lesion or other abnormal finding. Computerized tomography scan of the adrenal glands was normal. Clitoroplasty with preservation of neurovascular pedicles was performed for the treatment of clitoromegaly. CONCLUSION: The patients were diagnosed as "idiopathic isolated" clitoromegaly. To the best of our knowledge, there has been no detailed report about idiopathic clitoromegaly in the literature.

It should be performed at one sitting in advanced tumors. Defects caused by the resection should be closed with flaps which match in color, texture and hair bearing characteristics with the face. Cervicopectoral flap is a one such flap from chest and neck skin mainly used to cover the cheek defects. METHODS: This study included twelve patients presenting with cancer of the head and neck to Izmir Ataturk Training Hospital and Adnan Menderes University Hospital. Tumor resection and neck dissection was performed in one session by the same surgeon. A single incision was made and a medially based cervicopectoral fascio-cutaneous flap was used for surgical exposure in neck dissection and for closure of defects after tumor resection. RESULTS: There was no major complication. Two flaps had partial superficial epidermolysis at the suture line. Good aesthetic and funct...

Latissimus dorsi muscle has two arcs of rotation. It is classified as type V muscle. This muscle can be elevated on the thoracodorsal artery to cover large defects in the anterior chest and also, the muscle can be elevated on the segmental vessels to cover midline defects posteriorly. The aim of this study was to create a new arc of rotation on a vertical axis for the muscle and investigate effectiveness of vascular and chemical delays on the latissimus dorsi muscle flap with an inferior pedicle in an experimental rat model. We hypothesized that the latissimus dorsi muscle would be based on inferior pedicle by delay procedures. We tested two different types of delay: vascular and combination of vascular and chemical. We also tried to determine how many days of "delay" can elicit beneficial effects of vascular and combination delays in an inferior pedicled la...

It is essential that the defect should be covered with a tissue quite similar to the original one and is best achieved by harvesting tissue from an area adjacent to the defect. Tissue expansion is one of the most frequently used reconstructive techniques. A number of studies evaluated blood circulation, capsule formation, tissue tolerance, histomorphological changes and complications of expander placement. However, only a few attempted to enhance tissue expansion. This study we aimed to evaluate verapamil, a calcium channel blocker, to enhance tissue expansion. MATERIAL AND METHOD: Twelve New Zealand rabbits weighing between 900 gm and 1200 gm were assigned into study and control groups. High volume expanders (100, 200 or 300 cc) were placed into the subcutaneous tissue. Rabbits in the study group received verapamil. Expanders in the control group were in...

We also investigated this patient with a bone scan (normal), abdominal and cranial CT scans (also normal). Conclusion: Although metastasis of BCC is a very rare condition, this study reports a case of simultaneous parotid gland and lung metastasis originating from a giant BCC primary that was located on the right inner canthus of a 62 year old female.

We reviewed 264 burns cases treated in our departments to assess the frequency and clinicopathological features of this malignant complication. We found 31 cases of Marjolin's ulcer and a further 14 cases of nonmalignant ulceration at previous burn sites. Eighteen Marjolin's ulcers were located on the extremities, six on the scalp, six on the trunk, and one on the nose. Most malignancies were squamous cell carcinomas. The average time lag between the burns and subsequent malignant ulceration was 19 years. Four of the malignant ulcers had spread to regional lymph nodes, but there were no distant metastases. This study emphasizes that Marjolin's ulcer should be considered as a significant postburn complication.

Apart from a deformity that interferes with speech and mastication, operation may be indicated for cosmetic reasons. We have operated on five patients with double lip deformities for cosmetic reasons. Although a midline constriction band between two mucosal bulges is thought to be a constant feature, four of our five cases did not have a midline constriction. We used an elliptical excision of the mucosal excess in the four patients. The one with central constriction had an elliptical excision on each side, combined with a vertical midline Z-plasty to release the central constriction. Satisfactory aesthetic results were achieved in all patients.

Case Study: We report on a 34-year-old female patient with suicidal shotgun injury to her face delivered by a hunting rifle at close range into her mouth. She showed a large right cheek defect and a mandibular fracture. The defect was closed by a cervicopectoral fasciocutaneous flap; the mandibular fracture was managed with a titanium reconstruction plate. Good aesthetic and functional results were achieved 1 year after reconstruction. Conclusion: Early definitive reconstruction of shotgun injuries is still controversial. The cervicopectoral flap has many advantages. It is easy and secure to harvest and possesses skin properties similar to the face. The flap is quite thin allowing soft tissue coverage without a bulky view. This is the first study in the literature using a cervicopectoral flap for closure of a facial gunshot wound. We conclude that in patients with facial gunshot wounds, early reconstruction with a cervicopectoral flap offers a very important alternative.
