Common Signs and Symptoms of Cystic Basal Cell Carcinoma

Cystic basal cell carcinoma, a type of skin cancer, can manifest in various ways. Here are some common signs and symptoms to look out for:

• Bluish-black spot: A cystic basal cell carcinoma can present as a bluish-black spot that is slightly raised [7].
• Abnormal growth on the skin: The growth may have the appearance of a wart, crusty spot, reddish patch, mole, nodule or scaly lesion [8].
• Pearly bump: In some cases, it may start with a little pearly bump that looks like a flesh-toned mole or a pimple that does not go away easily [5].

Important Notes

It's essential to note that these symptoms can also be indicative of other skin conditions. If you notice any unusual growths or changes on your skin, it's crucial to consult with a healthcare professional for proper evaluation and diagnosis.

Diagnostic Tests for Cystic Basal Cell Carcinoma

Cystic basal cell carcinoma, a rare and aggressive form of skin cancer, requires accurate diagnosis to determine the best course of treatment. The following diagnostic tests are commonly used to diagnose cystic basal cell carcinoma:

• Skin Biopsy: A skin biopsy is the primary diagnostic test for cystic basal cell carcinoma. It involves removing a sample of tissue from the affected area and examining it under a microscope for cancer cells [1]. This test can confirm the diagnosis and help determine the extent of the cancer.
• Imaging Tests: Imaging tests such as X-rays, CT scans, or MRI scans may be used to evaluate the size and location of the tumor, as well as to check for any potential spread to other parts of the body [2].
• Histopathological Examination: A histopathological examination involves examining a tissue sample under a microscope to confirm the diagnosis and determine the type of basal cell carcinoma [3].

Staging and Classification

Cystic basal cell carcinoma is classified based on its risk of recurrence, which depends on the location of the tumor. It is considered high-risk if it has recurred after treatment or if there are multiple tumors present [4]. Staging the cancer can help determine the best course of treatment.

Differential Diagnosis of Cystic Basal Cell Carcinoma

Cystic basal cell carcinoma (BCC) is a rare variant of basal cell carcinoma, characterized by its cystic appearance. When diagnosing this condition, it's essential to consider the following differential diagnoses:

• Infundibulocystic basal cell carcinoma: This variant of BCC can also present with a cystic appearance and should be considered in the differential diagnosis (8).
• Trichoepithelioma: A benign adnexal tumor that can mimic the appearance of cystic BCC, particularly in its early stages (8).
• Basaloid follicular hamartoma: Another rare skin lesion that can present with a cystic or nodular appearance and should be considered in the differential diagnosis (8).

Key Features to Consider

When differentiating cystic basal cell carcinoma from these conditions, consider the following key features:

• Location and size of the lesion: Cystic BCC typically presents as a solitary, well-circumscribed nodule or cyst on the face or neck.
• Histopathological examination: A biopsy is essential to confirm the diagnosis. Histopathological examination can help differentiate cystic BCC from other conditions by identifying characteristic features such as peripheral palisading of cells and clefting (8).
• Clinical presentation: The clinical presentation, including symptoms and signs, should also be taken into account when making a differential diagnosis.
