TLDR
A patient with a clinically typical-appearing SK is described, which was biopsied and histologically proven to be a malignant melanoma arising in the SK, a reminder that the reliability of clinical diagnosis of SKs needs to be questioned.Abstract:
Seborrheic keratoses (SKs) are common benign nonmelanocytic epidermal tumors with characteristic clinical features, which are thought to allow a straightforward diagnosis in most situations. As a result, it is an accepted practice to destroy them without histopathologic confirmation. However, systematic reviews of histologic specimens reveal an erroneous clinical diagnosis or associated malignant tumors in a number of cases, including malignant melanomas. We describe a patient with a clinically typical-appearing SK, which was biopsied and histologically proven to be a malignant melanoma arising in the SK. Our report is a reminder that the reliability of clinical diagnosis of SKs needs to be questioned. In addition, a biopsy of SKs is not only warranted but necessary in order to identify a malignant melanoma that would otherwise be misdiagnosed or even completely missed.read more

TL;DR: The most helpful criteria in correctly diagnosing SK-like melanomas were the presence of blue-white veil, pseudopods or streaks, and pigment network, while hyperkeratosis and fissures and ridges were independent risk markers of dermoscopically SK- like melanomas.

TL;DR: The case of a patient with a lesion that initially revealed "classic" dermoscopic features of a seborrheic keratosis, but during follow-up, changes in color developed within the center of the lesions that led the clinician to the correct diagnosis of melanoma.

TL;DR: Generally, although the association between seborrheic keratosis and skin malignancy appears to be accidental, it must always be in mind that histopathologic examination of all seborRheic Keratosis should be considered, especially when sebor rheickeratosis has atypical clinical manifestations.

The status of the seborrheic keratosis.
TL;DR: Although these studies are inconclusive, lesions that are inflamed, bleeding, ulcerated, or sufficiently irritated may require being biopsied to rule out melanoma or other malignancies.

TL;DR: The term compound tumor is proposed to designate the finding of two distinctive neoplasms either directly contiguous with each other or immediately adjacent to each other in this association of malignant neoplasm.

TL;DR: Diagnostic ability of general practitioners and dermatologists concerning pigmented skin lesions in general and melanoma in particular was evaluated and thick melanomas were better recognized than thin melanomas in both physician groups.

TL;DR: The results confirm that melanoma can mimic seborrheic keratosis and strongly support the current policy of submitting for histological examination all specimens that have been removed from patients.

TL;DR: In this paper, the authors compared the diagnoses of general practitioners and dermatologists over a selected period in patients with a possible diagnosis of skin cancer, and found that over 50% of cases diagnosed clinically, the dermatologist and family practitioner agreed.

Basal cell carcinoma in seborrheic keratosis
TL;DR: Review of over 10,000 biopsies from SK revealed fourteen cases of basal cell carcinoma in seborrheic keratosis, and the material showed BCC in direct connection with the epidermis of the SK in eleven cases.
