Summary
A rare blue nevus presented as a large, dark oral lesion, mimicking malignancy. Histopathology confirmed the benign diagnosis, emphasizing its importance in differentiating oral pigmented lesions.
Area of Science:
- Oral Surgery
- Dermatopathology
- Oncology
Background:
- Blue nevi are benign melanocytic proliferations, uncommon in the oral cavity.
- Pigmented oral lesions can present diagnostic challenges, sometimes mimicking malignancy.
Purpose of the Study:
- To report a rare case of oral blue nevus.
- To highlight diagnostic challenges posed by large, pigmented oral lesions.
Main Methods:
- Clinical examination of a pigmented oral lesion.
- Incisional biopsy and histopathological analysis.
- Surgical excision and clinical follow-up.
Main Results:
- A 1.5 cm x 1 cm darkly pigmented macule on the hard palate was diagnosed as blue nevus.
- Histopathology revealed spindle cells with melanin pigment.
- Surgical excision resulted in satisfactory healing without recurrence at 5 months.
Conclusions:
- Oral blue nevi are rare and can mimic malignant lesions due to size and location.
- Histopathological analysis is crucial for accurate diagnosis of pigmented oral lesions.
- Clinical vigilance and follow-up are essential for managing such cases.

01:16Spinal Cord: Cross-sectional Anatomy
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

01:19Cranial Nerves: Overview and Anatomy
The cranial nerves are an important part of the complex network of nerves in the human body. These nerves emerge directly from the brain and are responsible for transmitting essential information between the brain and various parts of the head and neck. There are 12 pairs of cranial nerves, systematically numbered using Roman numerals from I to XII, beginning from the anterior and moving to the posterior of the brain. Each cranial nerve is uniquely identified by names that reflect its function...
