Penile melanosis, a benign condition causing hyperpigmented penile macules, can distress patients. Diagnosis is confirmed by basal keratinocyte hyperpigmentation, not melanocytic atypia, with conservative management often suitable.
Area of Science:
- Dermatology
- Pathology
Background:
- Penile melanosis is an uncommon, benign condition causing cosmetic concern.
- Patient distress can arise from the appearance of penile hyperpigmentation.
Observation:
- A case presented with annular penile macules exhibiting a distinct fibrillar pattern on dermoscopy.
- Clinical presentation involved hyperpigmented macules on the penis.
Findings:
- Histopathology confirmed basal keratinocyte hyperpigmentation without melanocytic proliferation or atypia.
- Diagnosis of penile melanosis was established through clinical, dermoscopic, and histopathological correlation.
Implications:
- Conservative management is a viable option for penile melanosis.
- Further case reports correlating clinical, dermoscopic, and pathological findings are needed to enhance understanding of this rare condition.

01:11Papillary 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.

The papillary layer is made of loose, areolar connective tissue, which means the collagen...

Anatomy of the Penis
The glans penis, or the head, is the terminal part of the penis and houses the external urethral orifice, the exit point for urine and semen. Covered by the prepuce, or foreskin, the glans is noted for its sensitivity and plays a key role in sexual pleasure. The body of the...
