Acne Infection

Acne Infection

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

Staphylococcal Skin Infections

Staphylococcal Skin Infections

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...

Skin Diseases and Disorders

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Accessory Structures of the Skin: Sebaceous Glands

Accessory Structures of the Skin: Sebaceous Glands

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...

The Skin Microbiota

The Skin Microbiota

The human skin serves as a complex ecosystem inhabited by a diverse community of microorganisms, including bacteria, fungi, and viruses. This microbiome plays a critical role in maintaining skin health and defending against pathogenic invaders. The composition of microbial communities varies significantly across different regions of the body, influenced primarily by the local levels of moisture and sebum.Regional Variation in Skin MicrobiotaCutibacterium acnes predominantly colonizes sebaceous...

Reticular Dermis

Reticular Dermis

The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

Area of Science:

Dermatology
Pathology

Background:

Folliculitis decalvans is an uncommon, chronic, and recurrent neutrophilic dermatosis.
It characteristically presents with pustules, crusts, and scaling follicular papules, often leading to progressive, irreversible scarring alopecia.
While scalp involvement is common, extensive cicatricial alopecia as the primary presentation is less frequently reported.

Purpose of the Study:

To report two rare cases of folliculitis decalvans presenting with extensive cicatricial alopecia.
To emphasize the clinical significance and diagnostic considerations of this unusual presentation.
To contribute to the literature on the spectrum of folliculitis decalvans manifestations.

Main Methods:

Case report methodology.
Clinical presentation review.
Histopathological examination of scalp biopsies (if performed).

Main Results:

Two patients presented with well-demarcated areas of scarring alopecia on the scalp.
The clinical appearance mimicked other forms of alopecia, necessitating careful dermatological evaluation.
The diagnosis was confirmed based on clinical and (if available) histopathological findings consistent with folliculitis decalvans.

Conclusions:

Folliculitis decalvans can present with extensive cicatricial alopecia, a rare but clinically significant manifestation.
Early diagnosis and appropriate management are crucial to prevent irreversible hair loss.
These cases underscore the importance of considering folliculitis decalvans in the differential diagnosis of scarring alopecias.
