Acral Metastasis of the Fingers: Report of 2 Cases.

Cutaneous metastases appear in 0.6% to 10.4% of malignant tumors and account for 2% of all cutaneous tumors.

Crohn's disease and Sweet's syndrome: A debut together.

The association of Sweet's syndrome and Crohn's disease is unusual, with less than 50 reported cases. We report a case in which these entities debut together.

Interstitial granulomatous dermatitis and arthritis revealing oesophageal carcinoma.

Interstitial granulomatous dermatitis and arthritis (IGDA) is an uncommon clinicopathological condition that may occur in association with a number of systemic disorders. We present a novel case of IGDA in association with oesophageal squamous cell carcinoma (SCC). A 67-year-old man with a 3-month history of arthritis presented with several erythematous indurated plaques on his lateral trunk and arms.

Chronology of metastasis in cutaneous melanoma: growth rate model.

In humans, it is not possible to obtain experimental evidence of when a cancer begins to metastasize. The purpose of this study was to estimate the time of onset of metastatic dissemination in cutaneous melanoma using a model based on its growth rate (GR). The critical time of onset of metastatic dissemination below which no cases of fatal melanomas were seen may be described with a potential function in which this time is inversely proportional to the GR.

[Pyoderma gangrenosum: a report of 15 cases and review of the literature].

Background: Pyoderma gangrenosum is a condition that is included among the neutrophilic dermatoses. Given its low incidence, few studies have addressed its epidemiology or treatment.

Objective: To describe the epidemiological and clinical characteristics of patients with pyoderma gangrenosum along with our experience of treating the condition in a referral hospital in Malaga, Spain.

[The current challenge of imported leprosy in Spain: a study of 7 cases].

Background: although the foci of leprosy once present in Spain are now under control and almost inactive, isolated cases are still occasionally diagnosed. Meanwhile, population migration has brought about an increase in the incidence of cases corresponding to individuals from countries where leprosy is endemic, leading to changes in the epidemiology of this disease.

Objectives: the aim of this paper was to describe the clinical, epidemiologic, dermatologic, microbiologic, and therapeutic characteristics of cases of leprosy in our department in the last 5 years.

Erosive pustular dermatosis of the scalp: a successful treatment with photodynamic therapy.

Erosive pustular dermatosis of the scalp (EPDS) is a rare inflammatory disease of unknown aetiology that usually occurs in the elderly. It is characterized by sterile pustules, chronic crusted erosions, cicatricial alopecia, and skin atrophy. The histopathology is nonspecific, and its pathophysiology remains undetermined, with various types of local trauma possibly acting as the triggering factor.

Growth rate as a prognostic factor in localized invasive cutaneous melanoma.

Background: Melanoma is a tumour with a very variable progression. Whilst some melanomas grow slowly over many years, others can reach several millimetres in thickness in just a few weeks. Since melanoma is a visible superficial tumour, the information obtained from the clinical interview may be of use to calculate the speed of growth of the melanoma.

Amicrobial pustulosis of the folds associated with Hashimoto's thyroiditis.

Neutrophilic dermatoses comprise a wide spectrum of diseases characterized histologically by the presence of an aseptic neutrophilic infiltrate in the skin. The neutrophilic infiltrate may move from the epidermis to the dermis and the subcutis, resulting in distinct clinicopathological conditions. There have been a few reports on a peculiar pustular dermatosis involving the cutaneous flexures and arising in patients with autoimmune diseases or immunological abnormalities.
