Summary
Melanoma can rarely present with comedo-like openings, a feature usually seen in seborrheic keratosis. Dermatologists must look for melanocytic criteria to accurately diagnose melanoma, even with non-melanocytic structures present.
Area of Science:
- Dermatology
- Oncology
- Dermoscopy
Background:
- Melanoma diagnosis relies on identifying specific melanocytic features.
- Pigmented lesions can exhibit diverse dermoscopic structures.
- Distinguishing melanoma from benign lesions is clinically crucial.
Observation:
- A case of melanoma displayed comedo-like openings on dermoscopy.
- Comedo-like openings are typically characteristic of seborrheic keratosis.
- This finding represents an unusual presentation for melanoma.
Findings:
- The presence of non-melanocytic structures does not exclude melanoma.
- Thorough dermoscopic examination is essential for accurate diagnosis.
- Specific criteria for melanocytic lesions should be prioritized.
Implications:
- Dermoscopists must remain vigilant for melanoma, even with atypical features.
- This case highlights the importance of a comprehensive diagnostic approach.
- Accurate melanoma diagnosis is critical for timely treatment and improved patient outcomes.

01:26Bone Markings
8.8K
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

5.2K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

01:28Types of Membrane Protrusions
3.0K
The protrusion of the cell surface is an initial step for several cellular processes, including cell migration, phagocytosis, and neurite outgrowth. These membrane protrusions are a result of cytoskeletal rearrangement. The most widely observed cell protrusions include lamellipodia, pseudopodia, filopodia, microvilli, invadopodia, and podosomes. These protrusions can be of two types — static or dynamic.

01:21Accessory Structures of the Skin: Sebaceous Glands
5.5K
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

2.5K
Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

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...
