Vulvar Acquired Melanocytic Nevus: An Obsolete Term

A vulvar acquired melanocytic nevus, also known as a mole, is a type of skin lesion that was once considered to be a rare and benign condition. However,

Diagnostic Tests for Obsolete Vulvar Acquired Melanocytic Nevus

The diagnosis of obsolete vulvar acquired melanocytic nevi typically involves a combination of clinical evaluation, imaging studies, and histopathological examination.

• Clinical Evaluation: A thorough physical examination by a dermatologist or gynecologist is essential to assess the size, shape, color, and texture of the nevus. The clinician will also evaluate the patient's medical history and any symptoms they may be experiencing.
• Imaging Studies: Imaging modalities such as ultrasound, MRI, or PET/CT scans may be used to rule out other conditions that could mimic a melanocytic nevus. However, these tests are not typically necessary for diagnosing benign nevi.
• Histopathological Examination: A biopsy of the nevus is usually performed to confirm the diagnosis and rule out malignancy. The histopathologist will examine the tissue sample under a microscope to look for characteristic features of melanocytic nevi.

Key Diagnostic Features

• Size: Benign melanocytic nevi are typically small, with diameters ranging from 1-7mm [15].
• Color: The color of the nevus can vary, but it is usually brown or black. Atypical melanocytic lesions may exhibit a combination of gray, blue, or white colors [11].
• Texture: The texture of the nevus is typically smooth and flat.

Differential Diagnosis

The differential diagnosis for vulvar acquired melanocytic nevi includes other pigmented lesions such as melanoma, which can be distinguished by its larger size, irregular shape, and presence of gray, blue, or white colors [11].

[15] İyidal et al. (2017) studied 10,047 acquired melanocytic nevi and found that the size of 98.3 percent nevi was less than or equal to 5mm.

[11] The presence of gray, blue, or white colors in a vulvar atypical melanocytic lesion is due to deeper lesions infiltrating the dermis, such as melanoma [11].

Based on the provided context, it appears that there are various treatment options available for vulvar acquired melanocytic nevi (moles). However, I couldn't find any specific information on "obsolete" treatments.

That being said, here are some treatment options mentioned in the context:

• Local excision [3]
• Laser therapy [13]
• Cryosurgery [3]
• Topical imiquimod 5% cream [3]

It's worth noting that these treatments may not be specific to "obsolete" vulvar acquired melanocytic nevi, but rather general treatment options for this condition.

If you're looking for information on outdated or obsolete treatments for vulvar acquired melanocytic nevi, I couldn't find any relevant information in the provided context. However, it's possible that some of these treatments may be considered obsolete due to newer and more effective treatment modalities being developed.

Some recent evidence suggests that novel treatment modalities such as checkpoint inhibitors and targeted therapies are also effective in treating vulvar melanoma [7]. However, I couldn't find any specific information on the use of these treatments for vulvar acquired melanocytic nevi.

In summary, while there are various treatment options available for vulvar acquired melanocytic nevi, I couldn't find any specific information on "obsolete" treatments. The most recent and effective treatment modalities may be considered more relevant in current clinical practice.

The differential diagnosis of an obsolete vulvar acquired melanocytic nevus can be challenging, but it involves considering various conditions that may present similarly to a benign melanocytic nevus.

Possible Differential Diagnoses:

• Seborrheic keratosis: A common skin lesion that can appear as a brown or black spot on the vulva. It is often mistaken for a melanocytic nevus, but it has a characteristic greasy appearance and may be accompanied by other symptoms such as itching or burning.
• Warts (Condylomata acuminata): A viral infection that can cause small, rough growths on the skin of the vulva. These growths can be mistaken for melanocytic nevi, but they are usually multiple and have a characteristic cauliflower-like appearance.
• Pigmented vulvar intraepithelial neoplasia (VIN): A type of precancerous lesion that can appear as a brown or black spot on the vulva. It is often associated with other symptoms such as itching or burning, and may be mistaken for a melanocytic nevus.
• Angiokeratomas: A rare skin condition characterized by small, dark red or purple spots on the skin of the vulva. These spots can be mistaken for melanocytic nevi, but they are usually multiple and have a characteristic "dotted" appearance.

Clinical Features to Consider:

• Solitary vs. Multiple Lesions: Vulvar acquired melanocytic nevi are typically solitary, while seborrheic keratoses, warts, and angiokeratomas may be multiple.
• Size and Shape: Melanocytic nevi are usually small (less than 1 cm) and round or oval in shape. Seborrheic keratoses and warts may be larger and have a more irregular shape.
• Color: Melanocytic nevi are typically brown or black, while seborrheic keratoses and angiokeratomas may have a lighter color.

Diagnostic Approach:

• Clinical Examination: A thorough clinical examination is essential to differentiate between these conditions. A biopsy may be necessary to confirm the diagnosis.
• Histopathological Examination: A biopsy of the lesion can help to distinguish between seborrheic keratoses, warts, and angiokeratomas from a vulvar acquired melanocytic nevus.

It's worth noting that the percentages of blue nevus lesions occurring on the upper limbs and hands, lentigo lesions on the feet, and "dysplastic" melanocytic nevus lesions on the lower limbs were higher than those in patients with a histopathological diagnosis of common acquired melanocytic nevi.
