Melkersson-Rosenthal syndrome (MRS) is a complex neuromucocutaneous disorder characterized by localized orofacial oedema and cranial nerve dysfunction, frequently associated with minor signs, including furrowed tongue. Complete forms are rare whereas mono- and oligosymptomatic variants are more common. A 71-year-old man presented with a 2-year history of relapsing and progressively persistent oedema of the right eyelids and periorbital region. A fissured tongue and telangiectatic rosacea had been present since the age of 50 and 60 years, respectively. The patient was also affected by essential hypertension and diabetes mellitus. A skin biopsy showed a marked upper dermal oedema, and small epithelioid cell granulomas arranged in perivascular and perilymphatic location. Collections of small epithelioid cells were occasionally observed within lymphatic spaces. No acid-fast bacteria, fungi or foreign bodies were detected. Intralesional corticosteroids induced transient improvement, whereas minocycline, clofazimine and dapsone have been ineffective. MRS may present with unilateral eyelid and periorbital swelling. Differential diagnoses of such cases may include a variety of cutaneous, ophthalmic and systemic diseases.

Exaggerated reactions to insect bites are characteristic of patients with haemoproliferative disorders, particularly chronic lymphocytic leukaemia (CLL). Skin lesions usually appear after the diagnosis of leukaemia and seem unrelated to laboratory findings, disease course or therapy. Rarely, the eruption may precede the diagnosis of the haematologic malignancy. The patients usually do not recall of insect bites, and the diagnosis may require histological and laboratory investigations to exclude specific lesions or autoimmune bullous diseases. Lesions may run a chronic course and represent a therapeutic challenge. Here, we report an adult patient with CLL who developed itchy recurrent papulovesicular and bullous lesions. Differential diagnosis was made with cutaneous specific lesions of CLL, bullous pemphigoid and pemphigus vulgaris, but laboratory and histological investigations confirmed the diagnosis of an insect bite reaction. The patient was treated with oral H1 anti-histamines and topical corticosteroids under occlusion, with marked improvement after 10 days.

Epidermodysplasia verruciformis (EV) is characterized by abnormal genetically-determined susceptibility to widespread and persistent infection of the skin with human papillomaviruses (HPV). The infection results in disseminated pityriasis versicolor-like lesions and flat warts. Skin malignant changes are very common and occur on sun-exposed areas. Several treatments have been used but without consistent benefit. Recently, retinoids and alpha-interferon, alone or in combination, have been reported to be of value in the therapy of EV lesions. We present the case of a 43-year-old white female affected by EV who developed multiple squamous cell carcinomas in the oral and genital mucosae during the previous four years. Both wart and cancer lesions harbored HPV24 along with the novel putative HPV type FA51. The patient was treated with a combination of acitretin (0.2 mg/kg per day) and peginterferon alfa-2b (1 microg/kg per week s.c.) for one year, with marked improvement of verrucous lesions and no recurrence of mucosal cancer. Thereafter, interferon was stopped whereas acitretin therapy was continued, but a new Bowen's disease developed in the perianal region, and the acitretin dose was increased at 0.5 mg/kg per day. At six-month follow-up, only a low number of flat warts persisted, and no clinical signs of cutaneous or mucosal carcinoma were evident.

Actinomycosis is a granulomatous suppurative bacterial disease caused by anaerobic actinomyces, which presents primarily with the cervico-facial, thoracic, abdominal or pelvic form. Cutaneous involvement is well documented and it is usually secondary to local extension or exceptionally to ematogenous spreading from visceral sites. Primary cutaneous actinomycosis is very rare and usually associated with external trauma and/or local ischemia. We report on the case of a primary cutaneous actinomycosis of the forehead in a 59-year-old man with diabetes mellitus who had had a preceding cranial trauma and several cutaneous reconstructive surgical procedures. The patient was treated successfully with combined antibiotic therapy.

The aim of the study was the investigation of the ability of L-acetylcarnitine (Acn; 1.5 g daily oral route for 1 month) to enhance some performances requiring a high level of attention and reflex velocity. The sample includes 17 healthy subjects, 8 males and 9 females, 22 to 27 years old; 10 of the subjects practice sports at agonistic level, while 7 have a sedentary life style. Reflexes have been measured, baseline and after 17 and 30 days of Acn administration, through a purposely constructed reflex-meter able to determine the latency (csec) of the reaction to an auditory stimulus. The ability as well as the time of learning was determined, before and after treatment, as the time and the number of errors to get out of the maze of a videogame (the test was also carried out by an untreated control group). Acn seems to induce an enhancement of reflex velocity, with complete annulment of the difference between the dominant and the opposite hand, as well as a significant reduction (3 to 4 times superior to controls) of both the errors and the time with the maze test.
