My contribution aims to describe an aesthetics of gesture based on Giorgio Agamben’s and Jean-Luc Nancy’s reflections about the relationship between gestures (as means of non-verbal communication) and medial-technological forms of production of sense. In the second part of my study I will analyse an installation of the artistic collective Studio Azzuro with the title In Principio (e poi) through the aforementioned aesthetics of gesture. Il presente studio tenta di delineare un’estetica del gesto a partire da alcune riflessioni di Giorgio Agamben e Jean-Luc Nancy circa la relazione tra i gesti (in quanto mezzi per la comunicazione non-verbale) e le forme tecnico-mediali di produzione di senso. Nella seconda parte del mio contributo analizzerò attraverso tale estetica del gesto un’installazione del collettivo artistico Studio Azzurro dal titolo In Principio (e poi).

A 33-year-old male patient comes to our observation for a slight discomfort in the left side of the tongue. The patient reported good general health and that he have sometimes taken benzodiazepine in periods of stress. The dental abrasion showed the presence of bruxism. On an objective examination we could notice the simultaneous presence of a "toothed tongue" and a slightly area of erosion on the left side of the dorsal tongue, with an irregular white halo around it. This lesion, appeared from some days, is symptomatic. The diagnosis is compatible for benign migratory glossitis. The patient claimed to have never suffered of skin diseases strongly related to migratory glossitis. It is possible that the bruxism may have determined the presence of that lateral tongue shape and that stress may be the main cause of the appearance of migratory glossitis. The simultaneous presence of the two conditions has never been documented in the scientific literature and we do not exclude that there may be a correlation to the genesis of both lesions. Sometimes the presence of a tongue with this morphology could be the result of a trauma or a surgery. The lingual erosion can be placed in differential diagnosis with a heat burn or a chemical burn.

A 64-year-old patient went to our private practice for a follow-up visit. The medical history reported mild hypertension, she was taking statins to control cholesterol and she reported to be positive for hepatitis B without however having had symptoms and signs of disease. She accidentally discovered through blood tests performed many years ago, to have contracted the HBV infection without realizing it and having overcome it. She has undergone tonsillectomy in adolescence. She had a very poor oral hygiene condition, partial upper and lower removable prostheses, and is a strong smoker (more than 20 cigarettes a day for decades). The patient presented dark pigmentations on the bilateral cheeks. On the soft palate there were pigmented areas, very large, brown in color and the patient, said to have noticed them since young, and that have not undergone evolution. The diagnostic hypothesis was smoke hyperpigmentation and probably the presence of the prosthesis did not allow the manifestation of it in the gingival tissues and in the hard palate. Pigmentations on the palate could be diagnosed with oral nevi, drug pigmentations or oral melanoma. We decided for a closely follow up of the patient, who did not want to be biopsied. We informed her about the possible risks of developing squamous cell carcinoma in heavy smokers.

A 42 years old male patient went to our observation for a white lesion in the left cheek presented 5 months ago. He reported general good health, a previous diagnosis of genital lichen planus. During the clinical examination we observed a white not scrapable lesion of 3 cm in the left cheek and 2 small esophitic lesions in the gingival tissue near the retromolar trigone, with cauliflower shape. The lesions is not linked with a traumatic event and we decided to make an incisional biopsy and 2 excisional biopsies for esophitic lesions on the gingiva, with a temporary diagnosis of leukoplakia and HPV squamous papilloma. The histological examination confirms instead the presence of an oral plaque lichen planus, without signs of dysplasia and the presence of 2 squamous papillomas on the tissue removed in the gingival. It is the first documented case in literature of an oral lichen planus which occurs many years after genital lesions, rare in a male subject. In addition, the simultaneous presence of HPV lesions in the same oral anatomic region is particular. Treatment includes topical therapy with podophyllin for HPV lesions or surgical excision and medical treatment of lichen planus with topical cortisones, immunosuppressants or aloe vera-based gels.
