Summary
Pigmented squamous cell carcinoma, a rare skin cancer variant, is infrequently documented globally. This report details a unique case from Brazil, emphasizing its clinical, pathological, and immunohistochemical features.
Area of Science:
- Dermatology
- Oncology
- Pathology
Background:
- Pigmented squamous cell carcinoma (PSCC) is an uncommon variant of squamous cell carcinoma (SCC).
- Limited cases of cutaneous PSCC have been reported worldwide, with none documented in Brazil.
- This highlights a significant gap in the literature regarding PSCC in this region.
Observation:
- The authors present a case of pigmented squamous cell carcinoma.
- Emphasis is placed on the detailed clinical presentation of the lesion.
- Pathological and immunohistochemical analyses were performed to characterize the tumor.
Findings:
- The case provides valuable data on the clinical and histological presentation of PSCC.
- Immunohistochemistry aids in differentiating PSCC from other pigmented skin lesions and SCC variants.
- This case contributes to the scarce global data on this rare entity.
Implications:
- This case report expands the understanding of pigmented squamous cell carcinoma in diverse populations.
- It underscores the importance of thorough clinical and pathological evaluation for rare skin cancers.
- Further research is warranted to elucidate the specific characteristics and behavior of PSCC, particularly in underrepresented geographical areas.

01:30Skin Cancer
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.

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...
