Folliculotropic mycosis fungoides: clinicopathological analysis of 17 patients.

BACKGROUND: Folliculotropic mycosis fungoides (FMF) represents a variant of MF characterized by hair follicle invasion of mature, CD4-positive small lymphoid cells with cerebriform nuclei. The disease displays resistance to standard treatment modalities and has an unfavourable course. OBJECTIVE: Clinical analysis of 17 patients with FMF collected between 2005 and 2012, investigation of tumour cells and involved hair follicle. METHODS: Re-evaluation of clinical data, wide panel immunohistochemistry investigation on paraffin-embedded biopsy material, T-cell receptor gene rearrangement analysis of the samples. RESULTS: Male and older age group predominance, frequent head-neck involvement, acneiform lesions, keratotic plugs, cysts, nodules, follicular papules, alopecia and classic mycosis fungoides-like plaques represented the main clinical characteristics. Treatment response showed a wide range from transient complete response to therapy resistance and death due to the disease. The pathological alterations: folliculotropism, mild epidermotropism, follicular plugging, mucinous degeneration of hair follicle, basaloid hyperplasia, syringotropism were similar to those observed previously. The first case of a CD8-positive folliculotropic mycosis fungoides - with unusual clinical presentation - is reported here. Nestin overexpression of mesenchymal cells of the isthmic and suprabulbar regions of hair follicle and the reappearance of dermal nestin-expressing cells were observed in association with immature dendritic cell hyperplasia. Altered CK19 expression was detected suggesting a potential role of follicular keratinocytes in the disease process. It was found that a proportion of neoplastic T cells constantly express programmed death-1 receptor in our patients contrary to classic mycosis fungoides. CONCLUSION: The spectrum of the clinical manifestation and the course of folliculotropic mycosis fungoides are broad and differ from classic mycosis fungoides. Folliculotropic neoplastic T-cell proliferation is associated with activation of inflammatory reactive T- and B-lymphoid cells, mesenchymal cells and changes in the hair follicle.

The evaluation of safety drain after cholecystectomy.

In the literature there views are controversial concerning the use of safety drain after the so-called ideal cholecystectomy. Some authors consider it necessary, while others superfluous. Authors wish to voice their opinion based on the analysis of their own material. In the last 5 years a total of 771 gallbladder operations were performed at their clinic. Of them 472 were judged retrospectively to be ideal cholecystectomies. The safety drain applied in these cases was brought out in a separate opening in 72.7% and in the line of the wound in 27.3%. In the former case healing was accompanied by wound infection in 3.2%, while in that of the drains introduced in the line of the wound in 8.5%. The quality and quantity of discharge through the drains were studied. In the majority of cases a small amount of bloody serum was conveyed by the drain tubes, this amounting on average to 45 ml. A larger amount was only noted in a few cases: 300-450 and 800 ml of bloody serum, in 3 patients. In one case there was a more serious bile leakage associated with fever, while in another patient arterial bleeding through the drain tube was observed. In diagnosing these and judging our tasks, drainage was of great help. Based on this experience, authors consider the use of safety drain justified.

Dystrophic epidermolysis bullosa complicated by cutaneous squamous cell carcinoma and pulmonary and renal amyloidosis.

A 25-year-old woman with Hallopeau-Siemens recessive dystrophic epidermolysis bullosa had generalized blistering, scarring and milia since birth. In the course of the disease, acral pseudosyndactyly developed, and the patient suffered from corneal erosions, oesophageal strictures, malabsorption, recurrent severe pneumonias and nephrotic syndrome. In addition, she had severe anaemia, sideropaenia, hypocalcaemia, heavy proteinuria and hypoalbuminaemia. A rapidly growing skin squamous cell carcinoma developed on the neck that spread to axillary and cervical lymph nodes. Recurrent hypocalcaemic tetanic convulsions and dyspnoea and a pneumonia refractory to antibiotics led to the premature demise of the patient. Autopsy revealed extensive amyloidosis of the renal, hepatic and splenic tissues. AA type amyloid deposits were detected in the renal glomeruli and in the lung, explaining the patient's unusually severe pulmonary infections. In essence, the patient had severe recessive dystrophic epidermolysis bullosa, complicated by squamous cell carcinoma, recurrent pneumonias and nephrotic syndrome due to secondary amyloidosis of the kidney and lung. The possibility of secondary pulmonary amyloidosis should be considered in severe dystrophic epidermolysis bullosa patients with recurrent pulmonary infections.
