Two Cases of Basal Cell Carcinoma Arising in Seborrheic Keratosis

The present study reports two cases of basal cell carcinoma arising in seborrheic keratosis. The first case is a seventy-three-year-old female who presented with a blackish nodule arising from a pigmented lesion on her chest. Histopathological analysis of the nodule and the pigmented lesion revealed a basal cell carcinoma with hair follicular differentiation and an acanthotic seborrheic keratosis, respectively. The second case is a seventy-year-old female with a blackish nodule arising from a pigmented lesion on her back. Histological analysis of the nodule revealed an atypical basaloid cell mass surrounded by a seborrheic keratosis lesion. In addition to the coexisting seborrheic keratosis with the basal cell carcinoma, a basaloid follicular hamartoma that showed muliple hamartomatous hair follicles or small cysts replaced by a branching cord or lace-like network of basaloid cells surrounded by fibrovascular stroma was identified. We concluded that both cases presented a rare combination of a seborrheic keratosis which underwent a malignant change to basal cell carcinoma. It appears that both basal cell carcinomas and seborrheic keratosis may derive from a similar source: pluripotential cells of either the epidermis or hair follicle epithelium.     

A Case of Pigmented Mammary Paget's Disease

Pigmented mammary Paget''s disease is a uncommon clinicopathologic variant of mammary Paget''s disease, and this mimics malignant melanoma both clinically and histopathologically. Herein, we report on a rare case of pigmented mammary Paget''s disease. An 81-year-old woman presented with 2.5×1 cm sized, red and brown, eczematous plaque on her right areola, and she''d had this lesion for 3 years. Histopathology showed large, atypical cells with large nuclei and abundant pale cytoplasm throughout the epidermis. Dispersed melanocytes were noted in the epidermis and some of the Paget''s cells contained melanin within their cytoplasm. Immunohistochemical studies demonstrated that the intraepidermal pagetoid cells were positive for cytokeratin 7; in contrast, they were negative for S-100, Periodic-acid Schiff (PAS), Alcian blue at PH 2.5, HMB-45 and carninoembryonic antigen (CEA). We recommend that pigmented mammary Paget''s disease should be included in the differential diagnosis of pigmented lesions on the nipple.     

Pigmented lesion in the inguinal region

Pigmented Bowen disease (PBD) is a rare tumor characterized by increased melanin pigment in the epidermis or papillary dermis in addition to the typical findings of Bowen disease. We report the case of a 60-year-old woman who presented with a 6-month history of a gradually enlarging solitary dark brown plaque in her right inguinal region. Histopathology showed hyperkeratosis with parakeratosis, acanthosis, disorganization of epidermal architecture, atypical keratinocytes, and increased melanin pigment of the papillary dermis. Considering the clinical and the histological evidence, a diagnosis of PBD was established. Complete resection confirmed the diagnosis. Pigmented Bowen disease is an unusual form of squamous carcinoma in situ. Other tumors in the differential diagnosis include pigmented basal cell carcinoma and superficial spreading melanoma.

Epidermotropic metastases from breast carcinoma showing different clinical and histopathological features on the trunk and on the scalp in a single patient

A 54-year-old female presented with the cutaneous metastases of the breast carcinoma that produced combination of pigmented zosteriform eruption on the trunk and eroded plaque on the scalp, 13 years after radical mastectomy. Histologically, zosteriform lesions displayed prominent infiltration of the epidermis in nesting or linear pattern by neoplastic cells with focal formation of intraepidermal and subepidermal vesicles due to discohesion of tumor cells and dermal edema. Examination of scalp plaque revealed ulcerations and infiltration of the epidermis with scattered basal and suprabasal malignant cells in pagetoid fashion. Immunohistochemically, tumor cells were cytokeratin 7- and estrogen receptor-positive and cytokeratin 20 negative. HMB-45 and Melan-A-stained numerous dendritic melanocytes intermingled with intraepidermal and superficial dermal tumor cells in the trunk lesion, whereas on the scalp, only occasional melanocytes surrounding intraepidermal carcinomatous cells were identified. Our case described, to our knowledge, so far unreported combination of individually rare, clinical and histological patterns of cutaneous metastases from breast carcinoma in a single patient.     

Metastatic myxoid melanoma with partial regression of the primary lesion

Myxoid melanoma is a rare variant of malignant melanoma. The diagnostic problems are obviously increased when it presents as amelanotic metastasis in a lymph node. An 82-year-old woman presented a subcutaneous mass in the right axilla. A thorough clinical investigation disclosed a pigmented black lesion on the right forearm. The right axillary lymph nodes and the pigmented lesion were resected. In the lymph nodes, proliferation of tumor cells with an abundant mucous substrate was noted. The cells proliferated in a variable pattern, and there were no melanin granules detected on hematoxylin-eosin-stained sections. However, we found melanin granules in the tumor cells observed under electron microscopy. In the pigmented lesion of the right forearm, there were small clusters of tumor cells with melanin granules, suggesting malignant melanoma. In the present case, myxoid metastasis occurred with the partial spontaneous disappearance of the primary nonmyxoid malignant melanoma.     

Co-existing basal cell carcinoma and blue nevus in an African-American woman

A 67-year-old African-American woman presented with an enlarging darkly pigmented plaque on her scalp. Histopathologic examination revealed a basal cell carcinoma juxtaposed to a blue nevus. Interestingly, the most common types of cutaneous collision tumors include melanocytic nevus and basal cell carcinoma. Whether these combinations are simply because of chance or may have a pathophysiologic mechanism is contentious. This is the first documented case of a basal cell carcinoma co-existing alone with a blue nevus.
