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.

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.

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.

Hepatocellular carcinoma(HCC) is the most common primary malignant tumour of liver. It is 5th most common malignancy in males and 8th most common tumour in females. The patients of HCC may remain clinically asymptomatic or may present with abdominal pain, weight loss, malaise, fever, jaundice or ascitis. HCC is a highly malignant tumor with frequent extrahepatic metastasis. The most frequent site of metastasis is lungs (47%), followed by lymph nodes (45%), bones (37%), and adrenal glands (12%). We present a case of 67 year old male, who presented with progressively increasing swelling in the left occipital region for 2 months. MRI brain showed large lobulated moderately enhancing T2 isointense to hyperintense and T1 hypointense mass lesion in occipital region, causing destruction of occipital bone with large intracranial extradural soft tissue component. Possibilities suggested were Meningioma or metastatic lesion. The scalp mass was excised. The histopathological examination of the excised tissue followed by elaborate immunohistochemistry suggested metastatic hepatocellular carcinoma, which was later confirmed by S.AFP and multiphase CT thorax, abdomen, pelvis which showed multiple liver lesions. Initial presentation of HCC as a subcutaneous lesion is very rare and only very few cases of HCC presenting with primary soft tissue swelling have been reported.
