Safety in dermatologic procedures: anaphylaxis, vasovagal reaction, and hyperventilation.

This article, part of a the series on safety in dermatologic procedures, covers the diagnosis, prevention, management, and treatment of 3 situations or conditions. The first condition we address is anaphylaxis, an uncommon but severe and potentially fatal reaction that must be recognized quickly so that urgent management coordinated with an anesthesiologist can commence. The second is fainting due to a vasovagal reaction, which is the most common complication in dermatologic surgery.

Multiple Perianal Ulcers Related to Use of a Hemorrhoidal Ointment With the Active Ingredients Triamcinolone Acetonide, Lidocaine, and Pentosan Polysulfate Sodium: A Series of 11 Spanish Patients.

The development of perianal ulcers related to the use of a hemorrhoidal ointment has not been reported in the literature. We describe a series of 11 patients who were treated for perianal ulcers in 10 Spanish hospitals after they used the same ointment containing the active ingredients triamcinolone acetonide, lidocaine, and pentosan polysulfate sodium. No prior or concomitant conditions suggesting an alternative cause for the condition could be identified, and after the patients stopped using the ointment, their ulcers cleared completely in 8 weeks on average.

Primary dermal melanoma: a case report and a review of the literature.

Patients with cutaneous metastatic melanoma of unknown primary origin (stage IV M1a disease according to the American Joint Committee on Cancer melanoma staging system) have an estimated 5-year survival rate of between 5% and 17.9% and a median survival of 6 months. However, certain patients with stage IV M1a disease have much higher survival rates.

[Presentation of 2 new cases of cutaneous angiomyolipomas and literature review].

We present 2 new cases of cutaneous angiomyolipomas with very similar characteristics, located in the postauricular region of 2 women aged 58 and 52 years. The lesions measured 1.5 cm and 1 cm across and had been present for 5 and 2 years, respectively.

[Pachydermoperiostosis (Touraine-Solente-Golé syndrome). Case report].

Pachydermoperiostosis or primary hypertrophic osteoarthropathy, also known as Touraine-Solente-Golé syndrome, is a rare process, frequently inherited. In its complete form it is characterized by pachydermia (thickening of the skin), skeletal changes (periostosis) and acropachia (digital clubbing). We report a patient that consulted for skeletal symptoms, as the acropachia and cutaneous manifestations (thickening of the skin of the face, scalp, hands and feet) went unnoticed due to their slow and progressive development.

[Spontaneous cutaneous umbilical endometriosis].

Endometriosis consists of extrauterine endometrial growths. Although it is usually located in the pelvis it can also be found in other sites. Endometriosis of the skin is rare and the most frequent form develops over gynecologic or obstetric scars, although it may also appear spontaneously in the umbilical area.

[Familial pemphigus vulgaris: immunogenetic study of HLA class II antigens].

Introduction: Pemphigus vulgaris (PV) is a rare autoimmune bullous disease that affects the skin and mucosae, characterized by the presence of antibodies against desmoglein 3, that causes acantholisis and formation of intraepidermal blisters. Observation of PV cases in several members of the same family suggests the existence of genetic factors that contribute to susceptibility to suffer the disease. However, very few cases of familial PV have been described.

[Stevens-Johnson syndrome/toxic epidermal necrolysis treated with intravenous immunoglobulins].

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are part of the same disease spectrum, but are differentiated by the degree of skin detachment. In TEN, more than 30 % of the body's surface area is affected; thus, it is a serious process, whose frequency is estimated at 1.2-6 cases per million population/year.

[Acquired paraneoplastic hypertrichosis lanuginosa].

Acquired hypertrichosis lanuginosa, an infrequent, paraneoplastic process, consists of the rapid development of lanugo-type hair, primarily on the face. We describe a 50-year-old woman with a 4-month case of hypertrichosis on the face and upper body, and weight loss over the last 6 months, in whom an inoperable squamous cell carcinoma of the cervix was discovered. Hypertrichosis lanuginosa is an indicator of a poor prognosis.

[Epithelioid sarcoma].

A description is given of an epithelioid sarcoma observed in a male patient of 71 years of age. This two-year growth was located in the right leg and presented a clinical picture of a hard walled ulcer. After having been removed surgically the tumour reappeared after seven months at which point amputation was practised at the middle thigh.
