“…The lesion highly mimicked the architectural pattern of KA, which was characterized by an exo‐endophytic lesion with a central keratotic horn with multilocular and multilobular patterns, and overhanging epithelial lip‐like structures with typical Bowen's disease. Pigmented as well as ordinary Bowen's disease usually shows flat, plaque lesions . The presented crateriform Bowen's disease may be similar to papillated Bowen's disease, which has been described as a rare, distinct variant of Bowen's disease .…”

The terminology and classification of keratoacanthoma (KA) and other types of squamous cell carcinoma (SCC) with crateriform architecture have not been clarified. The study evaluated the clinicopathological features of 41 nodular (exo-endophytic) SCC lesions with a central keratin-filled crater, including KA (well-developed stage). The lesions were histopathologically classified into six categories: (i) KA (well-developed stage) (27 lesions); (ii) KA-like SCC (three lesions); (iii) KA with malignant transformation (three lesions); (iv) infundibular SCC (crateriform) (four lesions); (v) crateriform SCC arisen from actinic keratosis (three lesions); and (vi) crateriform Bowen's disease (one lesion). The true characteristics of KA-like SCC remain unresolved, but there are three possibilities, namely, that it is one step in the evolution of KA, it is a borderline lesion between KA and invasive SCC, or it is one form of "KA with malignant transformation". KA, KA-like SCC, KA with malignant transformation and infundibular SCC (crater form) are considered to be hair follicle-related neoplasms. In contrast, crateriform SCC arisen from actinic keratosis and crateriform Bowen's disease are SCC, which are not related either to the hair follicles or KA. From an etiological standpoint, the presented lesions in these six categories are considered to be mixed up due to the similarity of crateriform architecture between the various types of lesions. However, the information provided in this report is intended to help physicians to make an accurate differential diagnosis of these conditions in clinical practice. The present study provides an opportunity to standardize the terminology for KA and related neoplasms.

“…Satter proposed that the pigmentation is due to the presence of an increased number of enlarged melanocytes with hypertrophic dendritic processes dispersed throughout the neoplasm [26]. It has been argued that incidence of pigmented BD has been underreported in the past [27]. Due to high sensitivity of dermoscopy in detecting pigmentory changes, newer studies have reported a much higher incidence of pigmented variant of BD, to the tune of 38–64% [28].…”

Bowens' disease (BD) is a precancerous condition of skin and/or mucosa with a predilection towards sun-exposed areas. Extensive literature research failed to reveal any case of multiple pigmented BD in type V Fitzpatrick skin. Multiple BD is a therapeutic challenge with a tendency to recur. Here we present an otherwise healthy Indian male having multiple pigmented lesions of BD on sun-protected sites of the body mimicking malignant melanoma. These lesions were refractory to treatment with different modalities. This paper is an attempt to review the available literature regarding the pigmented variant of multiple BD. Rationale for a therapeutic trial of UVB therapy for multiple arsenic induced BD is also discussed.

“…If present in excessive amounts, this pigment is also deposited in the dermis. 4 There are reports of association with seborrheic keratosis in 13.6% of cases, solar lentigo or more exuberant pigmentation of genital and intertriginous regions, found most commonly in sun-protected areas. 1 …”

“…4 The most sensitive dermoscopic findings are particularly important, such as amorphous brownish (if there is epidermal melanin), or grayish (if there is dermal melanin) pigmentation in addition to the more specific findings, which include brown dots in a regular arrangement at the periphery of the lesion and dotted or coiled vessels in a linear arrangement. 10 …”

Pigmented Bowen's disease is rare, though more prevalent in men. It presents as a well-delineated plaque in areas unexposed to sun. There are reports of association with seborrheic keratosis, solar lentigo or exuberant pigmentation of genital and intertriginous regions. A specific dermoscopy finding is the presence of brown or gray dots in regular arrangement and coiled or dotted vessels. Thus, we aim to raise awareness of the diagnosis of pigmented Bowen's disease in pigmented lesions.
