1. The skin through reflectance confocal microscopy -Historical background, technical principles, and its correlation with histopathology
Abstract Since its first introduction into medical practice, reflectance confocal microscopy (RCM) has been a valuable non-invasive diagnostic tool for the assessment of benign and malignant neoplasms of the skin. It has also been used as an adjunct for diagnosing equivocal cutaneous neoplasms that lack characteristic clinical or dermoscopic features. The us

2. Dermoscopy of annular elastolytic giant cell granuloma
Abstract Annular elastolytic giant cell granuloma is an uncommon granulomatous cutaneous disease that usually affects sun-exposed skin. Non-scarring alopecia is a possible presentation. Although histopathology is mandatory for the diagnosis, dermoscopy may help to narrow down the clinical differential diagnosis. The authors report a case of annular elastolyt

3. Necrotic erythema nodosum reaction associated with histological alterations of Lucio’s phenomenon
Abstract Patients with lepromatous or borderline leprosy may present two types of vasculonecrotic reactions: Lucio’s phenomenon (LP) and necrotic erythema nodosum leprosum (nENL). These are serious conditions, which mostly lead to life-threatening infectious and thrombotic complications. The authors report the case of a patient with leprosy recurrence asso

4. Choanal Polyps Originating from Unusual Sites: A Rural Tertiary Care Center Experience
Abstract Introduction Choanal polyps are benign lesions arising from the sinonasal mucosa, extending through the choana into the nasopharynx. Though polyps arising from the maxillary sinus and extending to the choana are common, polyps arising from the sphenoid sinus ostium, posterior part of middle turbinate, and inferior and middle meatus are quite uncomm

5. In vivo reflectance confocal microscopic findings in a case of trichofolliculoma
Abstract Trichofolliculoma is a rare follicular hamartoma whose dermoscopic features have been scarcely reported. On the other hand, reflectance confocal microscopy features have not been described yet. In the present study, the authors report reflectance confocal microscopy features in a case of trichofolliculoma as squamous hyperplasia forming irregular fi

6. Basaloid follicular hamartoma associated with follicular mucinosis and inflammation
Abstract Basaloid follicular hamartoma is a benign, superficial malformation of hair follicles that can be mistaken both clinical and histopathologically for basal cell carcinoma. Basaloid follicular hamartoma has been linked to a mutation in the PTCH-1 gene, which is part of the same pathway involved in Gorlin-Goltz syndrome. Here we present a 9-year-old pa

7. Breast carcinoma metastasis and Wolf’s isotopic response
Abstract Wolf’s isotopic phenomenon occurs when a new dermatosis appears on a site that has already healed from a previous dermatological disease of another etiology. This report describes the case of a 44-year-old female patient undergoing treatment for breast carcinoma who recently had brownish erythematous lesions appearing on the scar region of previou

8. Congenital solitary reticulohistiocytosis (Hashimoto - Pritzker)
Abstract Congenital and self-healing Hashimoto-Pritzker reticulohistiocytosis is the benign variant of the Langerhans cell histiocytosis (LCH) group. It is characterized by multiple skin lesions (congenital or appearing during the first days after birth), without systemic manifestations and spontaneous resolution in days to months. The authors report the cas

9. Cutaneous tuberculosis: epidemiological, clinical, diagnostic and therapeutic update
Abstract Tuberculosis is certainly one of the diseases considered to be ancient on planet Earth. The etiological agent of tuberculosis is Mycobacterium tuberculosis. This terrible bacterial infection still results in severe socioeconomic consequences to date, and its complete eradication represents a great challenge. It constitutes one of the most important

10. Osteolipoma of head and neck – a review
Abstract Objective: Due to the rarity of osteolipoma, current knowledge and understanding of its’ clinical presentation, management, radiological features, histological characteristics, and prognosis are lacking and can present a clinical conundrum to clinicians and histopathologist alike, given wide range of differential diagnoses. This paper aims to com

11. Extracranial non-vestibular head and neck schwannomas: a case series with the review of literature
Abstract Introduction: Schwannomas are tumous that arise from Schwann cells. Schwannoma is one of the differential diagnosis for lateral neck swelling. Objective: In this study, we aim to describe the incidence, presenting clinical features and management of extracranial, non-vestibular schwannomas of head and neck region, along with the review of the lite

12. Intraoperative frozen section performance for thyroid cancer diagnosis
ABSTRACT Objective: A primary medical relevance of thyroid nodules consists of excluding thyroid cancer, present in approximately 5% of all thyroid nodules. Fine-needle aspiration biopsy (FNAB) has a paramount role in distinguishing benign from malignant thyroid nodules due to its availability and diagnostic performance. Nevertheless, intraoperative frozen
