Basal cell carcinoma associated with non-neoplastic cutaneous conditions: a comprehensive review

Abstract

Box 1. Non-neoplastic cutaneous conditions associated with basal cell carcinoma.

Topical treatment of skin rashes in monkeypox owing to a jelly containing Mediterranean seasosings in tragacanth and arrowroot

“…BCC has also been reported to concurrently occur in the same skin location of several cutaneous conditions. This could be secondary to either the Koebner isomorphic response or the Wolf isotopic response in an immunocompromised district of the skin (Ruocco's immunocompromised cutaneous district) [3,7].…”

“…Basal cell carcinoma (BCC) is the most common human cutaneous malignant epithelial neoplasm [1][2][3]. BCC occurs in sporadic (non-syndromic) and syndromic (hereditary) forms.…”

“…In the first group, which comprises the vast majority of such cases, the affected individuals do not have any genodermatosis susceptible to developing cutaneous malignancies [2]. BCC is known to occur at the same skin location of neoplastic and nonneoplastic cutaneous conditions [3]. Multiple BCC's might occur at the same time (synchronously) or as one following the other with a time gap [2].…”

Multiple skin neoplasms at one site (MUSK IN A NEST): collision tumor consisting of epidermal (macular seborrheic keratosis) and dermal (lichen amyloidosis) components

“…MUSK IN A NEST, initially referred to as a collision tumor, can consist of two or more malignant neoplasms, one or more malignant and benign disorders, or two or more benign conditions [4]. Seborrheic keratosis and cutaneous amyloidosis have both been a component of a MUSK IN A NEST [4,6]. We suspect that a collision tumor consisting of a seborrheic keratosis and lichen amyloidosis has previously been observed; however, to the best of our knowledge, this is the first report of a MUSK IN A NEST that consists of these two dermatologic conditions.…”

Coexistence of osteoma cutis and seborrheic keratosis in a patient after botulinum toxin injection

“…pyogenic granuloma, malignant melanoma, atypical fibroxanthoma, pilomatrixoma, sebaceous nevus, and squamous cell carcinoma. [1][2][3] It may also be secondary to inflammatory skin diseases, acne vulgaris, trauma, or scar formation. 4 The pathogenetic mechanism of osteoma cutis has not been fully elucidated.…”
