Summary
Dermoscopy reveals key features of pigmented poromas, aiding in differentiating them from other skin tumors like basal cell carcinoma and melanoma. This study details vascular patterns and globule-like structures observed in pigmented poromas.
Area of Science:
- Dermatology
- Dermoscopy
- Oncology
Background:
- Limited knowledge exists regarding the specific dermoscopic characteristics of pigmented poromas.
- Pigmented poromas can present with diverse clinical and histopathological features.
Purpose of the Study:
- To investigate and describe the dermoscopic features of pigmented poromas.
- To aid in the differential diagnosis of pigmented poromas.
Main Methods:
- Retrospective analysis of 12 pigmented poroma cases.
- Evaluation of digital dermoscopic images for specific structures.
Main Results:
- Vascular structures were present in 8/12 cases, including hairpin, polymorphous, and arborizing vessels.
- Globule-like structures were observed in 7/12 cases, sometimes coexisting with arborizing vessels.
- Comedo-like openings were noted in 3 cases, consistently associated with hairpin vessels.
Conclusions:
- Pigmented poromas exhibit varied dermoscopic features.
- These features can lead to mimicry of other skin neoplasms such as basal cell carcinoma, seborrheic keratosis, and melanoma.
- Dermoscopy is a valuable tool for the diagnosis of pigmented poromas.

01:19Pigmentation
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
