Pink bodies with halo.

The presence of eosinophilic Toto bodies in oral lesions could be found in a variety of situations and sometime may present a challenge to the pathologist. We present three case reports where the oral biopsy was taken from the gingival region of a 30-year-old female, a 32-year-old male patient and another from the buccal mucosa of a 67-year-old male patient. Histopathologically, the three cases were finally diagnosed as pyogenic granuloma and moderately differentiated squamous cell carcinoma with the presence of clusters of Toto bodies in the upper spinous layer of stratified squamous epithelium.

Gorlin syndrome: A rare case report.

Gorlin syndrome is an autosomal dominant inherited condition that exhibits high penetrance and variable expressivity. The syndrome is caused by mutations in PTCH, a tumor suppressor gene that has been mapped to chromosome 9q22.3-q31. It is observed that most aggressive forms of keratocystic odontogenic tumor are the first signs of this syndrome which show a high recurrence rate due to its varied histopathological features. The other components are multiple basal cell carcinomas of the skin, intracranial calcifications and rib and vertebral anomalies. In addition, >100 minor criteria have been described with two major and one minor criteria or one major and three minor criteria necessary for confirmatory diagnosis. It is a rare syndrome having an estimated incidence of 1 in 50,000-150,000 in the general population with a 3:1 male/female gender predilection. Here, we report the case of a 14-year-old female patient diagnosed with Gorlin syndrome.

Leukaemic Transformation of Multiple Myeloma in Post Chemotherapy Remission Phase.

Plasma cell leukaemia is diagnosed when plasma cells are >20% in the peripheral blood. Plasma cell leukaemia may be present at the time of diagnosis (primary plasma cell leukaemia) or may evolve from multiple myeloma (secondary plasma cell leukaemia). We report case of a 62-year-old male who was diagnosed with multiple myeloma. He was treated with combination of prednisolone, melphalan and thalidomide. After 6 years he had Worsening of symptoms and also developed a scalp swelling. The swelling was diagnosed as plasmacytoma on fine needle aspiration cytology and confirmed on histopathology. Complete haemogram showed-Haemoglobin - 8g/dl, Total Leucocyte Count - 4300/µl, Differential leucocyte count - Neutrophil-40%, Lymphocyte-28%, Eosinophil-01%, Monocyte-10%, Atypical cells-21%, Platelet count- 1.5 lacs/µl. Peripheral blood showed rouleaux formation and plasma cells. Serum protein electrophoresis revealed an M spike (3.26 g/dl). So, patient was diagnosed as secondary plasma cell leukaemia. Weekly bortezomib and dexamethasone combination chemotherapy was given to the patient. Patient is on monthly follow up. Here we present a detailed case history of this patient.

Fibrosarcoma of maxilla: A rare case report.

Fibrosarcoma is a malignant tumor of fibroblasts. At one time, it was considered one of the most common soft tissue sarcomas. However, the diagnosis of fibrosarcoma is made much less frequently today because of the recognition and separate classification of other spindle cell lesions that have similar microscopic features. Of all the fibrosarcomas occurring in humans, only 0.05% occur in the head and neck region. Here, we present a case of 22-year-old female patient with the swelling on the left anterior aspect of the face. Histopathologically, the lesion was diagnosed as fibrosarcoma and immunohistochemically, the lesional cells showed positivity for vimentin.

Habit-associated salivary pH changes in oral submucous fibrosis-A controlled cross-sectional study.

CONTEXT: Oral submucous fibrosis (OSF) is a multi-causal inflammatory reaction to the chemical or mechanical trauma caused due to exposure to arecanut containing products with or without tobacco (ANCP/T). Arecanut and additional components such as lime and chewing tobacco render ANCP/T highly alkaline. Fibrosing repair is a common reaction to an alkaline exposure in the skin. OSF may be related to the alkaline exposure by ANCP/T in a similar manner. AIMS: The study was aimed at establishing the relationship of habit-associated salivary pH changes and OSF. SETTINGS AND DESIGN: The study design was controlled cross-sectional. MATERIALS AND METHODS: Base line salivary pH (BLS pH), salivary pH after chewing the habitual ANCP/T substance, post chew salivary pH (PCSpH) for 2 min and salivary pH recovery time (SpHRT) were compared in 30 OSF patients and 30 sex-matched individuals with ANCP/T habits and apparently healthy oral mucosa. RESULTS: The group's mean BLSpH values were similar and within normal range and representative of the population level values. The average PCSpH was significantly higher (P ˂ 0.0001) than the average BLSpH in both groups. There was no significant difference (P = 0.09) between PCSpH of OSF patients and controls. OSF patients had a significantly longer (P = 0.0076) SpHRT than controls. Factors such as age, daily exposure, cumulative habit years, BLSpH and PCSpH, had varying effects on the groups. CONCLUSIONS: Chewing ANCP/T causes a significant rise in salivary pH of all individuals. SpHRT has a significant association with OSF. The effect of salivary changes in OSF patients differs with those in healthy controls.

Intramuscular hemangioma of the oral cavity - a case report.

Haemangiomas are the most common benign soft tissue tumor of the oral cavity. It often presents at birth or soon after, and appears as a soft and vascular swelling in lip, tongue, or buccal mucosa. This article reports a rare case of intra muscular haemangioma of the buccal mucosa in a 27-year-old female patient.
