Pilomatricoma, pilomatrixoma, or calcified epithelioma of Malherbe is an uncommon, benign, isolated tumor of hair matrix primarily seen in children and young adults. The most common location is the head and neck region. It usually manifests as a small nodular mass. Here we report a rare case of giant pilomatricoma over the sternum in a 60-year-old male patient with an unusual clinical and radiological presentation mimicking a calcified sebaceous cyst.
The incidence of lung cancer has been increasing in the recent years. Bronchial cytology using Papanicolaou society of cytopathology (PSC) system is an effective method for triaging patients. The present study attempts to evaluate the bronchial cytological diagnosis with histopathological correlation of lung lesions. Aims: i. To study the cytological features of lung lesions. ii. To assess the sensitivity, specificity, and diagnostic accuracy of bronchial cytology of lung lesions in comparison with histopathology. Settings and Design: Prospective study at the tertiary care hospital. Methods and Material: It included 63 cases of lung lesions, evaluated using the PSC system for reporting respiratory cytology. The cytological diagnosis was correlated with the final histopathological diagnosis. The study was conducted between January 2019 and June 2020. Statistical Analysis Used: SPSS 20.0 software. Results: The sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of bronchial cytology was 60%, 89%, 90%, 58.62%, and 71.42%, respectively. Conclusions: Bronchial cytology including bronchial wash, bronchial brush, endobronchial ultrasound/transbronchial needle aspiration, and computerized tomography-guided fine needle aspiration cytology can be used to increase the sensitivity and specificity for definitive diagnosis and better management.
Scan to discover onlineBackground & Objective: Breast cancer is the most common cancer in developed and developing countries. This study mainly addresses the issue of an equivocal result in IHC, which then needs further assessment if the patient has to receive targeted therapy. The study aimed to detect the expression of Her2/neu protein in breast cancer by immunohistochemistry (IHC) and Fluorescence in situ Hybridization (FISH) and evaluate concordance and discordance between the two methods. Also, the clinicopathological parameters in these patients were studied in association with ER, PR, HER-2, and Ki-67.Methods: This study was conducted on 34 female carcinoma breast specimens, including core biopsies and mastectomies. Each case underwent histopathological and immunohistochemical studies for (Estrogen Receptor) ER, (Progesterone Receptor) PR, (Human Epidermal growth factor Receptor 2) HER-2, and Ki-67. In addition, FISH was done on all the samples to detect Her2 gene amplification. Results:The overall concordance between the two tests was 79.41% while the concordance between the two tests in equivocal cases, was 14.3%. ER/PR expression and HER-2 amplification were inversely associated. Also, Ki-67 expression was not associated with the side size of the lesion, lymphovascular invasion, and lymph node metastasis. Age less than 50 at presentation and infiltrating ductal carcinoma histological type showed increased proliferation index. Conclusion:The highest concordance between FISH and IHC was noted in IHC positive and negative cases, whereas IHC equivocal cases showed low concordance. FISH accurately determines the assessment of HER2 expressions in equivocal cases.
Pleomorphic carcinoma is a very rare subtype of pulmonary sarcomatoid carcinoma. It is an aggressive primary lung carcinoma that accounts for about <0.4% of lung tumors. The tumor usually recurs, resulting in a poor prognosis even after complete resection. Herein, we report an extremely rare case of an advanced pleomorphic carcinoma of the lung which was incidentally detected on autopsy as pulmonary tuberculosis. This patient did not have any clinical manifestations of either malignancy or tuberculosis when he was alive. This is extremely rare, being it an aggressive carcinoma that presents without any apparent symptoms.
Adrenal hemangiomas are rare vascular tumors. These are benign, mostly nonfunctioning and asymptomatic. Cavernous adrenal hemangiomas are more common in the elderly, with female preponderance. A computed tomography (CT) scan can diagnose their benign nature. Most cases are managed surgically, and laparoscopy is the most common approach followed nowadays.A young female presented with nausea, pain, and a vague mass palpable in the right abdomen. With CT findings favoring benign lesion or nonfunctioning adenoma but symptomatic, the patient had to undergo diagnostic laparoscopy and adrenalectomy. Adrenal hemangiomas are rare lesions. Moreover, involving a young female further makes their diagnosis difficult. Hence, they must be kept as one of the differential diagnosis in evaluation of adrenal mass in young females.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
