Concentration of FAD as a marker for cervical precancer detection.

We report the ex vivo results of an in-house fabricated portable device based on polarized fluorescence measurements in the clinical environment. This device measures the polarized fluorescence and elastic scattering spectra with 405-nm laser and white light sources, respectively. The dominating fluorophore with 405-nm excitation is flavin adenine dinucleotide (FAD) with a fluorescence peak around 510 nm.

Intrinsic fluorescence for cervical precancer detection using polarized light based in-house fabricated portable device.

An in-house fabricated portable device has been tested to detect cervical precancer through the intrinsic fluorescence from human cervix of the whole uterus in a clinical setting. A previously validated technique based on simultaneously acquired polarized fluorescence and polarized elastic scattering spectra from a turbid medium is used to extract the intrinsic fluorescence. Using a diode laser at 405 nm, intrinsic fluorescence of flavin adenine dinucleotide, which is the dominant fluorophore and other contributing fluorophores in the epithelium of cervical tissue, has been extracted.

Cytological diagnosis of pediatric thyroid nodule in perspective of the Bethesda System for Reporting Thyroid Cytopathology.

Background: Thyroid nodule is one of the most common endocrinopathies occurring children and adolescents. Though thyroid nodule is rare in the pediatric age group, the rate of malignancy is much higher in this age group compared to adult population.

Aim: The objective is to study the application of The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) in pediatric patients and compare the findings with histology.

Sclerosing mucoepidermoid carcinoma with eosinophilia of the thyroid: A cytological dilemma.

Sclerosing mucoepidermoid carcinoma with eosinophilia (SMECE) of the thyroid is a rare primary thyroid tumor arising in a background of Hashimoto's/lymphocytic thyroiditis and has been recently introduced in the World Health Organization (WHO) classification of thyroid tumors. It is characterized by extensive sclerosis, squamous and glandular differentiation, and inflammatory infiltrate rich in eosinophil. Here, we are discussing the cytological features of this rare case in a 35-year-old female presented with thyroid swelling and lymph-node enlargement.

Expression and clinicopathological significance of estrogen and progesterone receptors in gallbladder cancer.

Background: Clinical significance of sex hormone receptors in gallbladder cancer is not yet established. This study was performed to assess the expression pattern of estrogen and progesterone receptors in benign and malignant gallbladder lesions, and to assess their clinicopathological significance.

Methods: Tissue samples from resected gallbladder for cholelithiasis (n = 20) and carcinoma gallbladder (n = 25) were evaluated for estrogen and progesterone receptor (ER, PR) expression by automated immunohistochemistry.

Microfilaria in cytological smears at rare sites coexisting with unusual pathology: A series of seven cases.

Filariasis is a major public health problem in India and microfilaria is sometimes seen during routine fine needle aspiration cytology (FNAC) smears, but it is very rare to find microfilaria coexistent with neoplastic lesions. Here we report a series of seven cases in which microfilaria is associated with neoplastic lesions. Out of these seven cases one is benign and six are malignant.

Ependymoblastoma in an adult: a diagnostic challenge on cytology.

Ependymoblastoma is a rare, highly malignant brain tumour considered by most to be a subtype of primitive neuroectodermal tumour manifesting in young children. The authors present an unusual case of ependymoblastoma occurring in an 18-year-old female, one of the oldest patients reported with this tumour. The crush smears were highly cellular comprising singly scattered small, round immature cells with fine granular chromatin.

Tuberculosis verrucosa cutis developing over a keloid: a rare presentation.

Cutaneous tuberculosis can present as either primary or secondary infection, or it can be associated with systemic tuberculosis. It can present with unusual clinical and histological features causing delay in diagnosis and treatment. Tuberculosis verrucosa cutis occurs as a single verrucous lesion over exposed areas of the body along with inflammatory borders and discharging sinus.

Congenital granular cell tumor of the alveolar ridge.

Congenital epulis or neonatal granular cell tumor is a tumor whose histogenesis has long been debated. It is dissimilar to other granular cell tumors; the latter having derivation from Schwann cells and hence being S-100 positive. We report a case of congenital granular cell tumor in a newborn female child that was uneventfully operated.
