Monocytic aleukemic leukemia cutis.

The authors present a case of monocytic aleukemic leukemia cutis in which skin symptoms were the sole manifestation of the leukemia during the first year and a half of the disease. Diagnostic difficulties, the importance of immunohistochemical markers, and the prognosis and therapy of aleukemic leukemia cutis are discussed.

[Monocytic aleukemic leukemia cutis]. / Monocytaer aleukaemiás leukaemia cutis.

The authors present a 39 year old female patient with acute monoblastic leukemia, at whom during a year and a half the disease was manifested only with specific skin symptoms (leukemia cutis). Diagnostic difficulties, importance of immunhistochemic markers, as well as diagnostic, prognostic and therapeutic role of aleukemic leukemia cutis are discussed.

[Examination of the sentinel lymph node in malignant melanoma]. / A szentinel nyirokcsomó vizsgálatának jelentösége melanoma malignumban.

The authors report about a new "lymphatic-mapping" method (by means of patent blue staining) by which it is able to detect regional (sentinel) lymph node, into which the first metastasis is occurred. Experiences were made known with 15 patients. The by "lymphatic mapping" detected and removed sentinel lymph node has an, important role not only in determination of staging, but also in indication of prophylactic block-dissection, too.

[Perianal ulceration as the leading symptom of childhood Langerhans-cell histiocytosis]. / Perianalis fekély, mint a gyermekkori Langerhans-sejtes histiocytosis vezetö tünete.

The authors present a case history for a two-year-old boy in whom the study of perianal ulcer helped to diagnose the Langerhans cell histiocytosis. The authors emphasize the diagnostic value of intertriginous ulcers in identifying the above-mentioned disease.

[Polipoid melanoma]. / Polypoid melanoma.

Polypoid melanoma is a less known aggressive variant of nodular melanoma. It is characterised by earlier manifestation, exophytic growing, more frequent secundary alteration and whorse prognosis. On the basis of clinical and histological data of 14 patients, authors present characteristics of polypoid melanoma its differential-diagnosis and draw attention to the stressed importance of clinical diagnosis and treatment.

Scedosporium apiospermum infection imitating lymphocutaneous sporotrichosis in a patient with myeloblastic-monocytic leukaemia.

A 63-year-old man with a history of myeloblastic-monocytic leukaemia developed partly suppurating cutaneous nodules on the lower left leg. The nodules proceeded to spread in a linear fashion up the limb, following the line of the lymphatic drainage. Mycological examination of a skin biopsy demonstrated Scedoporium apiospermum. This case highlights the potential for Scedosporium species to act as opportunistic infections in immunosuppressed humans.

[Chronic renal failure with acquired perforating dermatosis]. / Chronische Niereninsuffizienz mit erworbener perforierender Dermatose.

A 50-year-old male patient suffering from renal failure was maintained in a stable condition by means of dialysis for 6 years. Hyperkeratotic papules appeared on his extremities. Histological investigation confirmed the diagnosis of perforating collagen disease. The dermatoses that are characterized by transepithelial elimination and associated with renal failure are discussed. The authors consider that the acquired perforating dermatoses should be regarded as a single entity.

[Scedosporium apiospermum infection in a patient with myelomonocytic leukemia presenting as lympho-cutaneous sporotrichosis]. / Lympho-cutan sporotrichosis formájában jelentkezö Scedosporium apiospermum fertözés myelo-monocyta leukaemiás betegen.

63 year old patient is presented with myelo-monocytic leukemia, in whom subcutaneous nodules developed at the lower limb, spreading along the lymph vessels, and partly ulcerating. By mycologic investigation Scedosporium apiospermum was disclosed. Attention is drawn to human infections brought about by opportunistic Scedosporium species.

Bacillary angiomatosis in a patient with lymphocytic leukaemia.

A 78-year-old man, who suffered from chronic lymphocytic leukaemia and diabetes mellitus, but was human immunodeficiency virus (HIV)-negative, developed disseminated angiomatous papules following a cat scratch. Bacillary angiomatosis was diagnosed by light and electron microscopic demonstration of the causative bacteria in the vascular lesions. The lesions resolved completely when he was treated with erythromycin. This case demonstrates that bacillary angiomatosis can be an important cutaneous manifestation of immunodeficiency in individuals who are not infected with the human immunodeficiency virus.

[Bacillary angiomatosis]. / Bacillaris angiomatosis.

In a 78 years old patient with chronic lymphoid leukemia, diabetes mellitus a cat scratch induced disseminated angiomatous papules were observed. In the lesions great number of bacilluses were observed with light -and electron microscope. As a result of antibiotic treatment the lesions regressed without trace. This opportunist infection resulting general symptoms as well, may be regarded as a cutaneous manifestation of immunodeficiency. The adequate antibiotic treatment depends on the exact diagnosis.
