Abstract
Cutaneous metastases are an unusual finding that may present as the first sign of an internal neoplasia. A case of cutaneous metastases of hepatocellular carcinoma, which may often involve other organs but very rarely metastases to the skin, is reported.

Abstract
Previously, we demonstrated that in vitro treatment of B16F10 murine melanoma cells with interleukin-2 (IL-2) enhances proliferation and metastasis. To further investigate the role played by IL-2 in human melanomas, we studied the expression of IL-2/IL-2 receptor and the effect of IL-2 on the proliferation of melanoma cell lines derived from primary (A375 and RMS cell lines) and metastatic (Hs294T cell line) tumours. We found a constitutive expression of cytoplasmic IL-2 and alpha, beta and gamma-subunits of the IL-2R on the surface of the three melanoma cell lines. The presence of IL-2 in the culture increased the proliferation rate in A375 and RMS cell lines, but no effect was observed in Hs294T metastatic cells. Biologically active IL-2 could be found in the supernatant of the three melanoma cell lines, particularly in A375 and RMS cells, in which an inhibition of the proliferation rate was observed when IL-2 was blocked. Moreover, the combination of anti-IL-2R beta and anti-IL-2R gamma blocking antibodies induced a significant down-regulation of cell proliferation in the three melanoma cell lines, and the combination of anti-IL-2R alpha, anti-IL-2R beta and anti-IL-2R gamma blocking antibodies inhibited IL-2-mediated growth stimulation in A375 and Hs294T cell lines. In RMS cells, a more significant effect was observed when only IL-2R gamma was blocked. Finally, exogenous IL-2 modulated the IL-2 endogenously produced by melanoma cells. These data show that IL-2 may modulate the growth of melanoma cells through autocrine or/and paracrine mechanisms.

Abstract
A boy born to a mother with unknown HIV infection was immunized with BCG in his first month of life. Seven months later axillary adenopathy developed. At the age of 10 months, 2 months after HIV infection had been diagnosed, papular skin lesions appeared all over his body. Mycobacterium bovis, BCG strain, was cultured from a lymph node and blood. Ziehl-Neelsen stain of a skin biopsy specimen showed histiocytes loaded with numerous acid-fast bacilli. The patient died 10 days later, before the infection was confirmed. This is the first reported case of disseminated BCG infection in an HIV-infected child presenting with cutaneous lesions.

Abstract
Bazex's acrokeratosis paraneoplastica is a clinically well-defined entity consisting of a distal erythemato-squamous eruption and nail dystrophy. It is always associated with neoplasia, mainly squamous carcinomas of the upper digestive and respiratory tracts; therefore, Bazek's acrokeratosis is considered to be a specific marker of internal malignancy. Two new cases of this syndrome are reported. The first was in a 41-year-old man with a squamous cell carcinoma of the oesophagus, the second in a 73-year-old man who presented with a transitional cell bladder carcinoma, an association not previously reported.

Abstract
Pseudocyst of the ear is a rare entity with controversial pathogenesis. Usually it is presented as a solitary, unilateral, fluctuant and non-inflammatory tumour of the ear with overlying normal skin. It occurs most often in young adult males. Incission reveals a serous liquid, with the consistency of olive oil, contained in the cyst-like lesion. Histopathology shows an intracartilaginous cavity with signs of degeneration and necrosis of the limiting cartilage. We present three new cases of this entity. Continuous minor trauma appears to be the causative factor in one of the patients, who also presented bilateral lesions.

Abstract
Focal dermal hypoplasia (Goltz syndrome) is a rare congenital syndrome with suspected X-linked transmission that is characterized by a wide range of mesoectodermal defects. We describe a 39-year-old woman who had a peculiar phenotype and asymmetry of the body. Examination revealed atrophic erythematous and hyperpigmented linear streaks following Blaschko's lines, some of which were in a reticular or cribriform arrangement. Yellow, soft nodules caused by fat herniation were visible mainly in skin folds. The patient had multiple bone anomalies, including longitudinal striation of long bones (osteopathia striata). She had several ocular, dental, and kidney defects. Histopathologic examination showed a markedly thinned dermis that was replaced by adipose tissue.

Abstract
We describe a patient with chronic actinic dermatitis whose photopatch tests revealed reactions to musk ketone and musk ambrette, both of which were found in his aftershave lotion. Minimal erythema doses of UVA and UVB were decreased. After initial unsuccessful treatment with PUVA therapy the patient was successfully treated with a combination of cyclosporine and PUVA.

Abstract
Enoxacin is a second-generation quinolone derivative recently introduced in Spain. Its activity comes through the inhibition of bacterial DNA-gyrase and it has a good antibacterial capacity against a broad spectrum of gram-positive and gram-negative bacteria. It is presumed to be less toxic than the rest of the quinolones and its use is increasing, specially to treat infections of the urogenital tract. Cases of photosensitivity to enoxacin have been very rarely reported. We describe 2 patients with photosensitivity reactions due to this drug.
