BACKGROUND: The incidence and mortality rates associated with cutaneous melanoma (CM) have steadily increased over the last 20 years. Even with successful treatment, melanoma patients usually experience substantial anxiety regarding the development of terrible recurrence. To date, few studies have investigated various dermatoses what the patients with CM had anxiety for the recurrence during postoperative surveillance (Dw). OBJECTIVE: To describe various Dw and to evaluate the risk of subsequent malignant skin disease in patients with CM...

Sebaceoma associated with seborrheic keratosis has only been described once in the literature. Herein, we present an additional case in a 69-year-old woman who complained of a multicolored plaque on the left breast. Dermatoscopy showed a central orange lesion with orange globules suggestive of dilated glands. The periphery of the lesion was brown and gray, with some more pigmented zones. The histopathological study demonstrated a seborrheic keratosis in the peripheral areas, whereas the central part of the lesion was a sebaceoma...

REVIEW
Andrew W Stamm, Kathleen C Kobashi, Ksenija B Stefanovic
PURPOSE OF REVIEW: Genital dermatology represents a challenge to many providers. Though dermatologic lesions involving the genitalia may present to any of a number of practices, ranging from primary care to urology, gynecology, and dermatology, few training programs provide significant training regarding the diagnosis and management of genital dermatologic lesions. The purpose of this review is to provide urologists with an overview of common genital dermatological lesions that may be encountered in a clinic...

BACKGROUND: Seborrheic keratosis (SK), a common and benign entity, is generally diagnosed clinically without the need for a biopsy. Given their variable appearance, SK may mimic cancer clinically and require biopsy for clinically equivocal cases. A clinician may also choose to perform biopsies on SK based on other circumstances, such as cosmetic reasons or SK being in an inconvenient and irritative location. METHODS: Dermatopathology samples from 2015 obtained from private and university locations were retrospectively assessed...

Hereditary hemochromatosis is an autosomal recessive disorder that disturbs iron metabolism and results in iron deposition throughout the body. Iron accumulation in various organs may cause a wide range of systemic symptoms and cutaneous manifestations of the disease are particularly striking. Classically, hereditary hemochromatosis has been termed "bronze diabetes." Although diffuse hyperpigmentation is a well-described feature of this disease, other cutaneous symptoms may also occur, and a variety of anomalies may be observed...

Clonal seborrheic keratosis (CSK) and pagetoid Bowen disease (squamous cell carcinoma in situ) (PBD) share similar histological features making it sometimes difficult to differentiate the 2. The study group included 29 and 13 cases of CSK and PBD, respectively. Both groups were examined histopathologically (suprabasal mitotic figures, broad rete ridges, crowding of nuclei, nuclear pleomorphism, necrotic keratinocytes, parakeratosis, and dermal inflammation) and immunohistochemically (CK10, Ki-67, and p16). P values for all parameters were calculated using Fisher exact test, 2 tailed...

REVIEW
Akane Minagawa
Making a definitive diagnosis of seborrheic keratosis (SK) can be challenging for the naked eye due to its wide variation in clinical features. Fortunately, however, most cases of SK exhibit the typical dermoscopic findings of fissures and ridges, hairpin vessels with white halo, comedo-like openings, and milia-like cysts, all of which are helpful to distinguish SK from melanoma, melanocytic nevus, squamous cell carcinoma, basal cell carcinoma (BCC) and other skin tumors. Histopathologically, these dermoscopic characteristics correspond to papillomatous surface of the epidermis, enlarged capillaries of the dermal papillae, pseudohorn cysts in the epidermis opened to the surface of the lesion and intraepidermal cysts, respectively...

Seborrheic keratoses are common benign epidermal lesions that are associated with increased age and sun-exposure. Those lesions despite harboring multiple somatic alterations in contrast to malignant tumors appear to be genetically stable. In order to investigate and characterize the presence of recurrent mutations, we performed exome sequencing on DNA from one seborrheic keratosis lesion and corresponding blood cells from the same patients with follow up investigation of alterations identified by exome sequencing in 24 additional lesions from as many patients...

A 79-year-old Japanese woman presented with an ulcerated, brown-red nodule in the center of a sharply demarcated, tan-brown plaque situated on the left side of her right breast. Histologically, the plaque demonstrated an acanthosis with an intraepidermal epithelioma of Borst-Jadassohn. Small oval nests of bland-appearing basophilic cells in the periphery gradually enlarged into nests of various sizes and irregular shapes, composed of densely cohesive, atypical basophilic cells above the central nodule. The atypical keratinocytes shifted to atypical spindle cells beneath the acanthotic epidermis, penetrating deep into the subcutaneous tissue...

BACKGROUND: Liquid nitrogen cryotherapy is a commonly used technique to treat a wide variety of dermatologic conditions including actinic keratoses, non-melanoma skin cancers, verrucae, and seborrheic keratoses. The risks associated with liquid nitrogen cryotherapy are important to know and discuss with patients prior to treatment. OBJECTIVE: We report a case of cellulitis secondary to liquid nitrogen cryotherapy for actinic keratosis. We sought to review the literature for an estimate of secondary infection rates following cryotherapy treatment...

Importance: Melanomas that clinically mimic seborrheic keratosis (SK) can delay diagnosis and adequate treatment. However, little is known about the value of dermoscopy in recognizing these difficult-to-diagnose melanomas. Objective: To describe the dermoscopic features of SK-like melanomas to understand their clinical morphology. Design, Setting, and Participants: This observational retrospective study used 134 clinical and dermoscopic images of histopathologically proven melanomas in 134 patients treated in 9 skin cancer centers in Spain, France, Italy, and Austria...

Differential diagnoses of pigmented lesions of the nipple include melanocytic nevus, melanosis of the nipple, seborrheic keratosis, pigmented basal cell carcinoma, melanoma and Paget disease. The histologic exam with appropriate immunohistochemistry is a fundamental tool to achieve a correct diagnosis. We present a patient with a pigmented lesion of her right nipple revealing mammary Paget disease and elucidate diagnostic obstacles and prognostic importance of early breast cancer detection.
