Lacrimal sac metastases from renal cell carcinoma.

PURPOSE: To report the first case of metastasis from renal cell carcinoma to the lacrimal sac and review the therapeutic options. METHODS: We have reviewed the case of a woman who was operated on for a renal cell carcinoma that developed epiphora and a lacrimal sac tumor, which corresponded to a metastasis from her previous tumor. Although renal cell carcinoma shows a great tendency for distant metastasis, this is the first reported case of metastasis to the lacrimal sac. RESULTS: We comment on the rarity of the case and on the therapeutic alternatives for these cases according to the reviewed literature. CONCLUSION: Metastasis to the lacrimal sac are rather infrequent and should be borne in mind on the appearance of a tumor in this location in people with a history of malignancy.

The temporalis muscle flap: an evaluation and review of 38 cases.

This article analyzes the authors' experience with the temporal myofascial flap in orbital, maxillary, floor of the mouth, tongue, retromolar trigone, and buccal mucosa reconstruction after oncologic surgery. Thirty-eight patients were treated and evaluated after using this technique. Four of the patients received the flap to restore orbital defects; the other 34 flaps were used in oral reconstruction. The flap remained viable in all instances. Most of the patients experienced no perioperative complications. Ten patients (29.4%) with flaps transposed to the oral cavity showed partial wound dehiscence. Two patients experienced temporomandibular joint dysfunction, two severe reduction in the oral aperture, 22 had mild depression of the temporal fossa, and four had mild to severe alteration in the facial aesthetics secondary to bone resection. All flaps transposed to the oral cavity showed good epithelialization and adaptation to the recipient site.

Sarcomas of the head and neck.

Fourteen cases of sarcomas involving the head and neck over a period of 15 years were reviewed. The male to female ratio was 3.5:1. Mean age of occurrence was 33.4 years, with a range of 5-84 years. Soft tissue was the site of origin in three cases, maxilla in four and mandible in seven patients. Radical surgery with resection of adequate disease-free margins was the most effective mode of treatment. Radiotherapy and chemotherapy was used in selected cases. Recurrence occurred in 42.9% of patients, and was the main cause of death. Three patients (21.4%) developed distant metastases. The actuarial 2-year and 5-year survivals of the 14 patients assessed were 64% and 56% respectively.

[Intravascular endothelial papillary hyperplasia in the masseter muscle]. / Hyperplasie intravasculaire endothéliale papillaire dans le muscle masséter.

Intravascular Papillary Endothelial Hyperplasia (IVPEH) is a benign process, even uncommon. It was first described by Masson in 1923 under the name "Hemangioendotheliom vegetant intravascular". We present a case of IVPEH located in the masseter muscle. The treatment for this lesion was surgical excision. The histological examination is very important in order to separate this lesion from angiosarcoma.

[Dens invaginatus]. / Diente invaginado.

Dens invaginatus is an abnormal enamel growth first described by Salter in 1855. It has an incidence between 0.4 - 10%, and the tooth most frequently affected is the lateral upper incisor. Its etiology is not explained. There are many asymtomatic cases and others with symptoms derived from periapical lesions. Treatment must be as conservative as possible. A bibliographic review has been made and we demonstrate a radiologic sequence of the many cases observed in our Service in the last two years.

[Occult tumors of the parotid gland and facial paralysis. A diagnostic problem]. / Tumeur occulte de la parotide et paralysie faciale. Un problème diagnostique.

The facial palsy produced by a parotid tumour, could be misdiagnosed due to the absence of a palpable mass or other any signs in the computerized axial tomography or nuclear magnetic resonance. However there are data derived from the facial anatomy, course and clinical characteristics from the palsy that could make us thinking on the presence of a parotid tumour. The objective of this article is to present this characteristics, together with a serial of clinic cases which coursed in the beginning with a facial palsy and had problems in their diagnostic. It's also remarked the significance of the presence or not of perineural infiltration to the parotid tumours that will condition not only the prognosis but also the clinic course.

Mandibular lesion as the first evidence of multiple myeloma. Case report.

Plasma cell dyscrasias affect the jaws relatively infrequently, and on rare occasions this is the first sign of the disease. This article describes the case of a patient aged 53 who presented with a lytic lesion in the right mandible which was initially diagnosed as an ameloblastoma. The diagnosis was made histopathologically and further investigation showed that the patient had multiple myelomatosis.

[Malignant nerve sheath tumor (malignant schwannoma). Presentation of a clinical case and review of the literature]. / Tumeur maligne des gaines nerveuses (Schwannome malin). Présentation d'un cas clinique et revue bibliographique.

The malignant schwannoma is a sarcoma which very rarely occurs on the face. This article describes the case of a woman with such a tumour and whose study and evolution shows that was no relation with the nervous trunk, neurofibroma or neurofibromatosis.
