In Wallonia, the incidence of cutaneous melanoma has steadily increased over the past decades. Hopefully, the early diagnosis made at the premetastatic stage has benefited from great advances both in the clinical and laboratory fields. Thanks to the "Groupement Oncologique Universitaire Wallonie-Liege" (GOUWL) organization, some efforts are currently made in order to better frame and normalize the management of cancer patients. Some medical staffs involved in prospective clinical research bring by their own experience further practical insights for the benefit to the patients. In this field, Belgium is not destituted. We report a brief review of the contribution of the Mosan Study Group of Pigmentary Tumors (GMETP) at the University Hospital of Liege. [less ▲]

The estrogen deficit occurring at menopause manifests itself under various modalities in the diverse organs and their functions. Skin does not escape this global involutive process. In addition to the effects of chronological ageing, sunlight exposure and other environmental and endogenous stimuli, the climacteric appears to exert some dramatic consequences on skin biology and aspect. The epidermis, its adnexae and the dermis are altered by this process. The epidermis may become xerotic and exhibits altered functions. The dermis thins out and its elasticity decreases in concert with the decline in bone mass. The skin microcirculation is impaired. These aspects are some of the better-worked out skin climacteric changes of which in turn seem to be stabilized or in part reversible with hormone replacement therapy (HRT). [less ▲]

The misdiagnosis of onychomycosis delays the proper treatment of the nail condition. Nail histomycology refers to the microscopic examination of histologic sections prepared from nail clippings for the purpose of detecting the presence of fungi. This laboratory method is the most sensitive procedure for the diagnosis of onychomycosis. It allows for the visualization of the precise location of the invasive fungus inside the nail apparatus. The method also distinguishes various shapes of the fungal cells, in particular filamentous fungi, yeasts, conidia, and sporodochia. The correct diagnosis provided by histomycology combined with culture not only allows for more efficient expenditure of funds and services but also is important for the timely alleviation of the disorder.

Basal cell carcinomas (BCC) are the most common malignant neoplasms in humans. Clinical misdiagnoses are not uncommon. These cancers are classified according to their histological and clinical characteristics which exhibit distinct malignant behaviours. It is important to be aware of the different clinical presentations both for the accurate diagnosis and tumour management. We report the case of a 78-year-old man, who presented an unusual pedunculated and pigmented BCC. This combined aspect is rarely encountered. [less ▲]

A 7-year-old, otherwise healthy Peruvian boy presented with a 3-month history of an indurated centrofacial plaque. Histologic examination revealed a granuloma containing free-living amebae tentatively identified as Balamuthia mandrillaris. The patient failed to respond to tentative treatment. He was admitted to the intensive care unit 7 months later with neurologic manifestations of granulomatous amebic encephalitis, which proved fatal. The difficulty in diagnosing this rare presentation of cutaneous amebiasis, the challenge of treating the condition, and the morbidity and high mortality associated with cerebral involvement are discussed.

It is acknowledged that tumour thickness, ulceration and lymph node invasion are the most important prognostic factors for cutaneous melanomas. Other histopathological features may also be informative. The aim of this study was to ascertain whether immunohistochemical methods can improve the detection of satellite micrometastases in primary melanoma patients. In addition, the predictive value of cutaneous satellite micrometastases for sentinel lymph node involvement was evaluated. A total of 265 primary cutaneous melanomas and 68 of the respective sentinel nodes were studied using a panel of seven antibodies directed against melanocyte-related antigens. In 12.4% of the 265 cases, small satellite micrometastases were detected by immunohistochemistry. Sentinel lymph node metastases were found in 14% of the 68 cases. Invasion of the sentinel lymph node correlated with the presence of cutaneous satellite micrometastases. It is concluded that the presence of cutaneous satellite micrometastases may be an indication for the performance of sentinel lymph node biopsy, and this finding calls for a closer follow-up of these patients.

BACKGROUND: Histological structures of the skin are often irregular in size and shape. Euclidean geometry and fractal analysis are complementary for assessing distinct aspects of their dimensions. OBJECTIVE: To determine and compare the variations in shape of the dermo-epidermal junction and the size of the superficial vessels in psoriatic lesions. METHOD: The relative microvasculature area and the fractal dimension D of the dermo-epidermal interface were measured inside and outside growth-stunted guttate lesions (n = 22) and expanding plaques (n = 37) in psoriasis of the trunk. RESULTS: The median D values of the dermo-epidermal interface were significantly larger (p < 0.01) in psoriatic plaques (D = 1.15) than in guttate lesions (D = 1.08), and these D values on lesional skin were significantly larger (p < 0.01) than in the uninvolved skin (D = 1.03). The microvasculature was significantly (p < 0.01) more developed in lesional (plaque: 13%, guttate: 8.20%) than in uninvolved skin (3.60 and 3.85%). No correlations were found between the relative microvasculature areas and the D values of the dermo-epidermal interface, both in the uninvolved and lesional skins of each psoriatic type. CONCLUSION: The absence of a relationship between modulations of the dermo-epidermal junction and vascular hyperplasia, both in expanding and stable psoriasis lesions, suggests that these events are regulated by different mechanisms and do not depend on each other.

Onychomycoses represent a group of nail affections caused by one or more fungi. Whether aging represents a risk factor for developing onychomycosis, remains a question. In the present work, we studied the variations in frequency and prevalence of onychomycoses and non-mycotic onychodystrophies according to age. Our results show that there is an increase in the frequency and prevalence of onychomycoses and non-mycotic onychodystrophies predominantly in patients over forty years of age. [less ▲]

The immune system plays a prominent role in the defense against a wide variety of pathogen fungi. Thus, the immunocompromised patient becomes a potential victim of mycoses originating from the skin. These mycoses may become invasive and a fatal issue is possible. In other circumstances, the inoculation site is pulmonary or digestive, and the cutaneous lesions represent secondary localizations.

Aspergillus species are important fungi of the environment, some of them being responsible for severe infections. Many distinct diseases form the human aspergillosis spectrum. The pathomechanisms differ according to the affected organ and the immune status of the patient. The fungus can be responsible for allergic reactions. It may also act as a saprophytic colonizer of air spaces. Infection may remain limited to the skin and nails. It may also be invasive, particularly in immunocompromised patients, in the lungs, paranasal sinus and gastro-intestinal tract. Hematogeneous disseminated aspergillosis represents another dramatic form of the disease. [less ▲]

There is increasing awareness of the population about the risk of cutaneous melanoma. In recent years, some improvement was gained in the early recognition of clinical warning signs using dermoscopy. As a result, the number of puzzling cases exhibiting limited classical clues for malignancy are submitted to the dermatopathologist. Thus, the risk of microscopic uncertainty or misdiagnosis may be increasing. The aim of the study was to assess retrospectively the contribution of immunohistochemistry in establishing the histological diagnosis of 520 melanocytic neoplasms. According to the disease evolution and the histological presentation, 6 profiles of phenotypical expressions were distinguished. [less ▲]
