SummaryMyiasis is a general term for infection by fly larvae feeding on the host's necrotic or living tissue. Although infestation by fly larvae is much more prevalent in animals, it is a relatively frequent in occurrence. Oral myiasis is a rare pathology in humans and is associated with poor oral hygiene. Larvae cause itching and irritation due to their crawling movements and can destroy vital tissues, inducing serious or even life-threatening haemorrhage. The treatment is a mechanical removal of the maggots one by one; however, a systemic treatment with macrolide antibiotics, have been recently used for treatment. We present a case report of a 70-year-old man indigent, alcoholdependent with an extensive necrotic wound in mandible and fetid odour. The prevention of human myiasis is by education, but unfortunately in the developing countries some people live in low social condition, predisposing the occurrence of the infestation. BACKGROUND

Trifid mandibular condyle is an exceptionally rare entity, diagnosed accidentally on radiographic examination. Its etiology is controversial. Dental professionals should have knowledge of this anatomic abnormality and of the problems caused by it in normal function, as well as appropriate treatment modalities. In the literature, only three such cases have been reported. The current case report (the fourth reported) is of a unilateral trifid condyle reported in a 37-year-old woman seeking treatment for a missing tooth. A panoramic radiograph accidentally revealed a discrete modification of the right mandibular condyle. Computed tomography (CT) with 3-D construction was done to confirm the diagnosis.

Dentists who use orthopantomographs may play a vital role in screening patients with osteoporosis, mainly among post menopausal women.

Ancient schwannoma is considered as a variant of schwannoma, comprising about 10% of all schwanommas. Schwannoma is a benign neoplasm derived from the nerve sheath of peripheral motor, sensory and sympathetic nerves and from the cranial nerve pairs. It usually presents as a solitary soft-tissue lesion which is slow growing, encapsulated and is often associated with nerve attached peripherally. Diagnosis is often confirmed with the microscopic examination. The long standing schwannoma attributes to degenerative changes and is termed "ancient" schwannoma. Present case is of a 68-year-old female patient who reported with an asymptomatic large swelling below mandible on the left side since last 23 years. The lesion was surgically excised under general anesthesia.

SUMMARYPapillary cystadenocarcinoma (PCC) is an uncommon malignant tumour of the salivary gland, sometimes involving the minor salivary gland. Previously this entity was classified as an atypical type of adenocarcinoma, malignant papillary cystadenoma, low-grade papillary adenocarcinoma or mucus producing adenopapillary carcinoma. PCC is a glandular tumour with an indolent biological behaviour characterised by cysts and papillary endophytic projections. We report two cases of PCC involving the minor salivary gland of the hard palate. Both the patients presented with a swelling in the palate with difficulty in chewing. MRI revealed an extensively destructive lesion involving hard palate, alveolar ridge and maxillary antrum. Clinical and radiological features suggested the malignant nature of the lesion. Histopathology of incisional biopsy revealed tumour proliferation in a multicystic pattern, with extensive papillary proliferation. Diverse and cellular cytomorphology, and cellular and nuclear pleomorphism with few mitotic figures were the prominent features. Both the lesions were confirmed as PCC. BACKGROUND
