Basal cell carcinoma with halo phenomenon in a young female: Significance of dermatoscopy in early diagnosis

Indian Journal of Dermatology, 2015
Halo phenomenon of nevus may be observed as a circular reaction, although it is unusual around tumors. A 29-year-old woman presented with a pigmented lesion on the cheek since three years.

Giant congenital melanocytic nevus with neurotized lesions mimicking neurofibromas – A rare presentation

Indian Journal of Paediatric Dermatology, 2020
Giant congenital melanocytic nevus (GCMN) is a deeply pigmented lesion, often associated with hypertrichosis and multiple scattered satellite lesions. During infancy apart from textural changes, rapidly growing “proliferative nodules” mimicking melanoma ...

Balloon cell melanoma: a case report with polarized and non-polarized dermatoscopy and dermatopathology

Dermatology Practical & Conceptual, 2014
Balloon cell melanoma is a rare melanoma subtype, with only one previous case with dermatoscopy published. It is often non-pigmented, leading to diagnostic difficulty, and there is a tendency for lesions to be thick at diagnosis.

Woolly Hair Nevus Associated with Sebaceous Nevus and Linear Pigmentation

Indian Journal of Paediatric Dermatology, 2023
Abstract The term woolly hair nevus was first described and coined in 1927 by Fred Wise. It is a nevoid condition characterized by a circumscribed patch of unruly and curled hair with an altered texture and may be associated with other nevoid conditions.

Giant congenital melanocytic nevus with neurofibroma-like lesions and onset of vitiligo

Journal of Dermatology and Dermatologic Surgery, 2015
Giant congenital pigmented nevus and neurofibromatosis type 1 may rarely occur together. We reported here an unusual case where giant congenital melanocytic nevus was associated with neurofibroma-like lesions and vitiligo, emphasizing the clinical and ...

The usefulness of c-Kit in the immunohistochemical assessment of melanocytic lesions

European Journal of Histochemistry, 2011
C-Kit (CD117), the receptor for the stem cell factor, a growth factor for melanocyte migration and proliferation, has shown differential immunostaining in various benign and malignant melanocytic lesions.

Performance of a Deep Learning Algorithm for Melanoma Classification Across Diverse Dermoscopic and Tele‐Dermatology Datasets

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Early detection of melanoma significantly boosts patient survival rates. Deep learning has demonstrated dermatologist‐level accuracy in assessing pigmented skin lesions by analysing images at the pixel level. However, these neural networks may face challenges with ‘real‐life’ images due to limited training data and image artefacts ...

Reduced Visibility of Pigment Network Under Sub‐UV Reflectance Dermatoscopy Compared to Polarised Dermatoscopy: A Novel Diagnostic Clue to Differentiate Melanomas From Nevi

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Melanoma accounts for more than 75% of skin cancer‐related mortality. Dermatoscopy is an evidence‐based technique for earlier detection, yet differentiating melanocytic lesions remains challenging. Sub‐UV reflectance dermatoscopy (sUVRD) uses purple light (405 nm) to visualise chromophore distribution in the skin.
