Nevus sebaceous of Jadassohn is a congenital cutaneous hamartoma with epidermal, sebaceous, follicular, and apocrine structures that usually appears at birth or in early childhood. It has the potential to generate a variety of secondary neoplasms of different lineages, and the risk increases with patient age. Although multiple neoplasms may occasionally arise within the same lesion, the coexistence of more than five secondary tumors is extremely rare. Here we report a case of seven secondary tumors including syringocystadenoma papilliferum, desmoplastic trichilemmoma, sebaceoma, trichoblastoma, pigmented trichoblastoma, sebaceous adenoma, and tumor of follicular infundibulum arising within a nevus sebaceous. The complete diagnosis relies on the histopathological analysis of multipoint biopsies and delicate pathological sections.

Background: Skin cancer has a remarkable importance given the high incidence in the population. In Brazil, it is estimated that there were 98,420 new cases of non-melanoma skin cancer among men and 83,710 new cases among women in 2014. Objectives: To verify signs and symptoms present in patients with skin neoplasms according to the literature and relate them to the nursing diagnoses of NANDA International. Materials and Methods: Integrative literature review carried out from March to May 2015 in the databases: Cumulative Index to Nursing and Allied Health Literature, SCOPUS, National Library of Medicine and Nattional Institutes of Health, Latin American and Caribbean Sciences of Health and Web of Science. The descriptors used were: 'Signs and Symptoms' and 'Skin Neoplasms'. Sixteen articles were identified as the final sample. After review, the signs and symptoms of skin cancer identified in the literature were related to the defining characteristics present in NANDA International, with the aim to trace possible nursing diagnoses. Results: The most prevalent signs and symptoms were: asymmetric and well circumscribed nodules with irregular borders; speckles with modified color aspect; ulcerations; blisters; pain; itching; and bleeding. The principal nursing diagnoses outlined were: risk for impaired skin integrity; impaired skin integrity; acute pain; risk of shock; and impaired comfort. Conclusions: The identification of signs and symptoms present in patients with skin cancer and the relationships of these with the nursing diagnoses of NANDA International provide a basis for qualified and systematized nursing care to this clientele.

Side effects of tattoos can occur due to unexpected body responses. Concerns about the side effects of tattoos are growing concomitantly with the increasing number of tattooed individuals. We report a rare case of basal cell carcinoma (BCC) on a tattooed eyebrow. A 48-year-old woman with no family history or occupational risk of skin cancer had her eyebrows tattooed 6 years prior, and she noticed a black mass on her right eyebrow 1 year before presentation. Staged excision was planned due to the patient's reluctance regarding the possibility of a wide scar. After the first surgical procedure, a histopathological examination confirmed BCC. Wide excision and primary closure were performed for remnant BCC, and no recurrence was observed. The mechanism of skin neoplasms involving tattoos has not been clearly identified. Unapproved tattoo inks contain carcinogenic substances, and previous case reports indicate that skin neoplasms may differ depending on the tattoo color. Therefore, the carcinogenic effects of these unknown components of tattoo ink might cause skin neoplasms. Accurate component analysis and systematic management of tattoo ink is necessary, and medical practitioners must also pay attention to this possibility because it is easy to overlook tattoos as a causal factor contributing to cancer.

Skin metastasis from papillary thyroid carcinoma is extremely rare. Due to similar histopathologic features, it is difficult to differentiate skin metastatic papillary thyroid carcinoma and some primary skin neoplasms without a clinical history. However, most of metastatic skin lesions showed a strong reactivity to the antithyroglobulin antibodies unlike primary skin neoplasms. Metastatic skin lesions must be completely removed and radiotherapy can be added. Investigators reported that prognosis of skin metastases from thyroid carcinoma is dismal and the average survival after it's diagnosis was only 19 months because distant metastases were often discovered at diagnosis of skin metastasis or during follow-up period. We report a case of skin metastasis from tall cell variant of papillary thyroid carcinoma. In our case, the anti thyroglobulin antibodies measured from cystic fluid from a skin lesion was more than 2000 IU/ml. Skin metastasis was diagnosed at 20 months after primary surgery for thyroid cancer and brain metastasis at 12 months after diagnosis of skin metastasis. Although skin metastasis is an ominous prognostic indicator in patients with thyroid carcinoma, a radical treatment for skin lesions and early diagnosis of distant metastasis could provide a chance to the patients to improve their survival.

Reconstruction of the lower limb presents a complex problem after skin cancer surgery, as proximity of skin and bone present vascular and technical challenges. Studies on vascular anatomy have confirmed that the vascular plane on the lower limb lies deep to the deep fascia. Yet, many flaps are routinely raised superficial to this plane and therefore flap failure rates in the lower limb are high. Fascio-cutaneous flaps based on perforators offer a better cosmetic alternative to skin grafts. In this paper, we detail use of a thermal imaging camera to identify perforator 'compartments' that can help in designing such flaps.

Sebaceous neoplasms are rare adnexal tumors that can present a challenge to clinicians. Only four cases of sebaceous carcinoma with sebaceoma have been reported in the literature. Herein, we describe the case of a sebaceous carcinoma originating from a sebaceoma in a solitary nodule of the posterior neck. Immunohistochemically, the tumor cells were strongly positive for epithelial membrane antigen and p53. It is possible that adnexal carcinomas may arise from malignant transformation of their benign counterparts as well as de novo. Malignant transformation was likely in this case because the lesion was composed of distinct benign and malignant components, and the benign component showed the typical histopathological features of sebaceoma. This case underscores the fact that partial and superficial biopsies sometimes may not provide the correct diagnosis. If a surgeon suspects malignancy based on a clinical examination, then it is mandatory to perform a deep biopsy.

Cutaneous squamous cell carcinoma (cSCC) is the second most common nonmelanoma skin cancer, and its incidence is increasing globally. In Korea, there were 12,516 diagnosed cases of cSCC between 1999 and 2014. Surgical treatment, for which several options are available, is the standard of care for cSCC and securing a sufficient surgical resection margin is always important. cSCC of the scalp sometimes exhibits unusually aggressive behavior. In this article, we report a case of cSCC of the scalp with invasion into the skull and dura mater.

Mucoepidermoid carcinoma is one of the most common malignant tumors that occur in the salivary glands. While several cases of distant metastasis have been reported, instances of metastasis to the skin are rare. We present the case of a 72-year-old man diagnosed with parotid mucoepidermoid carcinoma who experienced temporary remission following surgical resection and adjuvant chemoradiotherapy. However, the carcinoma recurred along the skin at the periauricular area along the mask line. Given the current prevalence of COVID-19, the practice of wearing masks has become more widespread. This case report highlights the recurrence of mucoepidermoid carcinoma along the mask strap line, emphasizing the importance of distinguishing it from benign dermatological conditions.

This study examined the relative incidence of feline cutaneous tumors according to age, breed, sex, and site predilection for these tumors. Biopsy samples were examined and diagnosed from the histopathology. Over a 72-month period, from January 2013 to December 2018, 478 feline biopsy samples were received from veterinary practitioners across the nation. Of these, 232 (48.54%) cases were skin masses. Among them, 73.71% (171/232) were neoplastic lesions and 26.29% (61/232) were non-neoplastic. Twenty-two different types of cutaneous neoplasms were diagnosed as epithelial tumors (15.79%), mesenchymal tumors (83.63%), or melanocytic tumor (0.58%). The four most common tumors were mast cell tumor (60.23%), lipoma (5.85%), basal cell carcinoma (4.68%), and fibrosarcoma (4.68%), which comprised 75.44% of all tumor cases. Cutaneous tumors were located most commonly in the head of the cat (43.27%) and in the Korean shorthaired breed (75.44%). According to this study, cutaneous tumors were the most common tumor types in feline neoplasms in Korea. The incidence of cutaneous tumors was highest in Korean shorthaired cats, the most prevalent breed in Korea. Mast cell tumors are the most common skin neoplasm in Korea and can affect very young cats.
