    Optimizing suction blister epidermal graft technique in the surgical treatment of vitiligo.
    An Bras Dermatol 2017 Nov-Dec;92(6):888-890
    Department of Dermatology at Hospital Santa Casa de Curitiba - Curitiba (PR), Brazil.
    Surgical management of vitiligo is considered an excellent terapeutic option for recalcitrant cases, provided the disease is stable and there is absence of Koebner phenomenom. Among surgical modalities, Suction Blister Epidermal Graft is a low cost and effective option (65 to 100% repigmentation can be achieved in up to 80% of patients). We describe how it can be optimized by using an alternative suction equipment, by customization of graft format and by application of an anesthetic technique that substantially reduces procedure time.

    Dermatology Department. University Hospital San Cecilio, Granada, Spain.
    Dermoscopy is a non-invasive technique widely used to aid in the characterization and diagnosis of pigmented skin lesions. Recently, it has also been employed for the evaluation of non-pigmented skin tumours, and inflammatory and infectious cutaneous diseases. Although the diagnosis of cutaneous leishmaniasis is confirmed by the demonstration of amastigotes in infected skin or by the growth of promastigotes in culture medium, dermoscopy could be useful as a further diagnostic test.

    Cancer immunology and melanoma immunotherapy.
    An Bras Dermatol 2017 Nov-Dec;92(6):830-835
    Sírio-Libanês Hospital Oncology Center - São Paulo (SP), Brazil.
    The stimulation of the immune system, in order to generate an attack against cancer cells, similarly to that which occurs in infectious disease, has long been matter of interest in oncology; however, only limited success has been achieved, with different treatment strategies tested in recent years. The development of new immune checkpoint inhibitors is currently changing this scenario, and immunotherapy is becoming a real choice among traditional cytotoxic treatments to fight cancer. Recent reports have shown efficacy and safety with the use of pembrolizumab, nivolumab, and ipilimumab for the treatment of different neoplasms, especially melanoma. Read More

    Usefulness of the subunit principle in nasal reconstruction.
    An Bras Dermatol 2017 ;92(5 Suppl 1):159-162
    Department of Dermatology (Mohs surgery) of Hospital Santa Casa de Curitiba - Curitiba (PR), Brazil.
    The subunit principle in nasal reconstruction proposed the concept of reconstructing the specific topographic subunits that were identified as dorsum, tip, columella, the paired alae, sidewalls, and soft triangles. In patients with more than 50% of subunit loss, removing the remaining portion of the subunit and reconstructing the entire subunit may yield better results. The placement of incisions along the borders of the subunits minimizes scar lines. Read More

    An Bras Dermatol 2017 ;92(5 Suppl 1):154-158
    Department of Medical Genetics, University of Antwerp, Universiteitsplein - Antwerp, Belgium.
    Inherited Palmoplantar Keratodermas are rare disorders of genodermatosis that are conventionally regarded as autosomal dominant in inheritance with extensive clinical and genetic heterogeneity.

    Department of Dermatology. Hospital Universitario Central de Asturias, Oviedo, Spain.
    Trigeminal trophic syndrome is an uncommon cause of facial ulcers, that affects the sensitive area of the trigeminal nerve. We present the case of an 84-year-old patient with ulcerated facial trigeminal trophic syndrome, and report the development of a clinico-dermoscopic approach for his clinical examination. The value of this model for the diagnosis of facial ulcers suspected to be a rodent ulcer basal cell carcinoma is suggested. Read More

    The importance of direct immunofluorescence in pemphigus herpetiformis diagnosis.
    An Bras Dermatol 2017 ;92(5 Suppl 1):145-147
    Dermatology Outpatient Clinic at Hospital do Açúcar de Alagoas do Centro Universitário Tiradentes, Maceió, Alagoas (AL), Brazil.
    Pemphigus herpetiformis is an autoimmune bullous disease, that combines clinical features of dermatitis herpetiformis and linear IgA bullous dermatosis and immunological characteristics of pemphigus, which makes this disease peculiar and this diagnosis rarely suspected in the first evaluation of the patient. The reported case is of a patient with clinically bullous disease similar to dermatitis herpetiformis, whose multiple biopsies were inconclusive, and only after direct immunofluorescence with a pemphigus pattern (intraepidermal intercellular pattern) the confirmation of the diagnosis was possible. Read More

    "String of pearls pattern": report of three cases of non clear-cell acanthoma.
    An Bras Dermatol 2017 ;92(5 Suppl 1):142-144
    Department of Introduction to Clinic, School of Medicine, Universidad Autónoma de Nuevo León (U.A.N.L) - Nuevo León, Mexico.
    The coiled and dotted vessels in a serpiginous arrangement or "string of pearls" is considered a classical vascular pattern associated with clear cell acanthoma. We present three cases of epidermal tumors different from clear cell acanthoma that have the same "string of pearls" vascular pattern. Even though most authors keep considering the "string of pearls" vascular pattern an almost pathognomonic sign of clear-cell acanthoma, the cases presented here suggest that some other epidermal tumors can also show this pattern.

    Numerous infectious, inflammatory and neoplastic complications secondary to tattoo placement have been reported in the literature. Within inflammatory complications sarcoidal granulomatous reactions have been described. We report two cases, a 55-year-old woman with yellowish infiltrated plaques on bilateral ciliary region, 16 years after the placement of a permanent tattoo in the eyebrows, and a 20-year-old tattoo artist who developed orange papules on 3 of his tattoos.

    Reconstruction of surgical defect of the dorsum of the hand.
    An Bras Dermatol 2017 ;92(5 Suppl 1):132-134
    Dermatological Surgery Outpatient Clinic of the Department of Tropical Dermatology of Hospital Central do Exército (HCE) - Rio de Janeiro (RJ), Brazil.
    In some cases, keratoacanthomas can be indistinguishable from squamous cell carcinoma, making the gold standard treatment surgical excision with histopathological evaluation. The surgical defects created on the back of the hand can be challenging to repair. We describe the use of bilateral rotation flap as an option in this area, and discuss the indications and contraindications of some of the possible surgical techniques for reconstruction of the dorsum of the hand.

    Pyoderma gangrenosum associated with left iliac vein compression syndrome: presentation of difficult diagnosis.
    An Bras Dermatol 2017 ;92(5 Suppl 1):129-131
    Department of Dermatology at Escola Paulista de Medicina, Universidade Federal de São Paulo (EPM-Unifesp) - São Paulo (SP), Brazil.
    Pyoderma gangrenosum is a rare neutrophilic dermatosis of unknown etiology, of which the most frequent clinical manifestations are ulcers. The diagnosis difficulty is, among other things, to rule out other causes of ulcers, since it is considered a diagnosis of exclusion. Skin ulcerations may also occur in the iliac vein compression syndrome, which, like pyoderma gangrenosum, mainly affects young women. Read More

    Pretibial dystrophic epidermolysis bullosa.
    An Bras Dermatol 2017 ;92(5 Suppl 1):126-128
    Department of Dermatopathology of the Department of Anatomic Pathology, Santa Casa de Misericórdia de São Paulo - São Paulo (SP), Brazil.
    Epidermolysis bullosa is a group of mechano-bullous genetic disorders caused by mutations in the genes encoding structural proteins of the skin. Dystrophic epidermolysis bullosa is caused by mutations in the COL7A1 gene encoding collagen VII, the main constituent of anchoring fibrils. In this group, there are autosomal dominant and recessive inheritances. Read More

    Porokeratotic eccrine and hair follicle nevus: a report of two cases and review of the literature.
    An Bras Dermatol 2017 ;92(5 Suppl 1):121-125
    Department of Dermatology, Complejo Hospitalario de Navarra - Pamplona, Spain.
    Porokeratotic eccrine and hair follicle nevus is a very rare non-hereditary disorder of keratinization with eccrine and hair follicle involvement with only 9 cases described in the literature. In 2009 the term porokeratotic anexial ostial nevus was proposed to comprehend porokeratotic eccrine and hair follicle nevus and a related and more common process without follicular involvement: porokeratotic eccrine ostial and dermal duct nevus Recent findings suggest that both entities may be produced by a mutation in GJB2 gene, which is associated to KID syndrome. Herein we report 2 cases of porokeratotic eccrine and hair follicle nevus and review the existing cases in the Spanish and English literature. Read More
