[Malignant melanoma of the mandibular gingiva]. / Le mélanome malin de la gencive mandibulaire.

INTRODUCTION: The oral melanoma (OM) account for 1% of all melanomas. The prognosis is poor despite an adequate locoregional control of the disease. OBSERVATION: A 47 year old women consulted for a blackish lesion of the mandibular gingiva next to tooth 37. Intraoral examination showed a dark pigmented lesion on the lingual side of the left mandibular molar region, extending from tooth 37 to the trine retro left molar. The biopsy confirmed the diagnosis of mucosal nodular melanoma. A wide surgical excision without ipsilateral neck dissection was performed. The treatment was completed by 30 Gy external beam radiotherapy, the patient died 18 months after the first consultation. DISCUSSION: Oral melanomas have a poor prognosis probably because they are generally detected late. The most common sites for oral melanomas are the palate and maxillary gingival, malignant melanoma of the mandibular gingiva is extremely rare. About 30% of OM is preceded by areas of oral pigmentation for several months or years. The prognosis is poor with a 5% to 20% five-year survival rate.

[Pott's puffy tumor, a rare complication of frontal sinusitis]. / Tumeur de Pott, complication rare de la sinusite frontale.

Port's puffy tumour (PPT), corresponding to frontal osteomyelitis causing erosion of the anterior wall of the frontal sinus and subperiosteal abscess, is a rare but serious complication of frontal sinusitis or trauma to the region. It can occur even despite the use of antibiotics and requires surgical drainage of the abscess, excision of pathological tissues and obliteration of the frontal sinus by various materials. It can rarely progress to life-threatening intracranial extension. Practitioners must be extremely cautious in the presence of clinical signs suggestive of Pott's puffy tumour. The aim of this article is to present a case of progressively evolving PPT in a patient of 28 years by frontal headaches that are aggravated by painful swelling front soft and fluctuating by palpation and that has fistulated at the right upper eyelid. CT scan of the face revealed the presence of a discontinuity bone at the anterior wall of the right frontal sinus. The treatment consisted of surgery and antibiotics. The patient remained asymptomatic after a decline of 18 months.
