Cystic lesions are common in the head and neck. The most common are the cutaneous cysts, which are referred to as epidermal cysts. These cysts present as nodular and fluctuant subcutaneous lesions and they are seen most commonly in the acne - prone areas like the head, neck and the back. They arise following a localized inflammation of the hair follicle and occasionally after the implantation of the epithelium, following a trauma or surgery. The presence of benign cystic lesions in the salivary glands is rare.We are presenting a rare case of a 55-year-old male who presented with a soft swelling on the left side of the face. A diagnosis of an epidermoid cyst was given on cytology. A superficial parotidectomy was performed and the histopathology confirmed the above diagnosis.

Mucoepidermoid carcinoma (MEC) is a rare malignant tumor arising from the bronchial gland. A case of 6-year-old male child who presented with fever, hemoptysis and wheezing since 1month is reported. Chest X-ray showed features suggestive of foreign body with post-obstructive pneumonia and was treated for the same with medication without much improvement. Subsequently computerized tomography scan chest was carried out, which showed oval mass with speculated margin in right hilar region with distal segmental atelectasis. Bronchoscopy showed small growth with nodularity in the apical segmental bronchus of the right lower lobe with mucosal erosion and hence carried out broncho-alveolar lavage showed few atypical squamous cells. Patient underwent right lower lobectomy, which showed a grey white oval mass with solid and cystic areas in the right hilar region with extension in to the lung parenchyma. Histology of the tumor showed mixed solid and cystic areas with sheets of epidermoid cells and mucus-filled cysts of irregular size. Areas of solid growth were composed of squamoid and intermediate cells. Hence, the final diagnosis of mucoepidermoid carcinoma (MEC) intermediate grade of the lung was made. Early diagnosis can be accomplished if the clinician is alert to persistent pneumonia, coughing and tumor obstruction on image studies. MEC is a comparatively rare low-grade tumor, which reportedly carries a good prognosis with early surgical intervention.

BACKGROUND Histopathological study of colonoscopic biopsies is a well-established and cost-effective diagnostic test for evaluation of colonic lesions. It also contributes significantly to the pre-operate investigation of patients with colonic lesions .The main objective of the study is to scrutinize all colonoscopy biopsies and to study the Histopathology of colonic lesions and the spectrum of various colonic lesions and their prevalence in patients presenting to tertiary care hospital in South Karnataka. A total of 150 colonoscopic biopsies was studied in a 2-year period in the Department of Pathology, K. S. Hedge Medical Academy. METHODS Patients presenting with symptoms of pain abdomen, chronic altered bowel habits, haematochezia were examined by flexible colonoscopy after receiving consent from the patient. Biopsy specimen were mounted on a filter paper, fixed in formalin (10% solution of formaldehyde) and then processed. Sections of 3-4 µ were mounted on a clean glass side and stained with haematoxylin and eosin (H&E) stain. Special stains like PAS, GMS, MTS, Ziehl Neelsen (ZN) etc., were used whenever indicated. RESULTS Age of the patients ranged from 3 years to 87 years with a mean age of 47.65 years. Majority of the patients were males (83 cases) with a male to female ratio of 1.23:1. Among 150 cases, 92 cases (61.3%) were non neoplastic lesions and 58 cases (38.7%) were neoplastic lesion. The ratio of non-neoplastic to neoplastic lesion was 1.58:1. CONCLUSIONS The incidence of colonic lesions is increasing in recent years with early onset of inflammatory bowel disease and colorectal neoplasm in relatively younger age group due to changing life style and dietary habits.
