    Trigeminal trophic syndrome: an important simulator of discoid cutaneous lupus erythematosus - a case series
    (2020) RESENDE, Ludimila O.; DWAN, Alexandre J.; NICO, Marcello M. S.
    Trigeminal trophic syndrome occurs secondary to trigeminal nerve injury, leading to anaesthesia and paraesthesia, with consequent vigorous facial skin manipulation and lesion production, simulating other facial diseases such as ulcerative discoid lupus erythematosus, tumours and other artificially produced lesions. Ulceration and destruction of the ala nasi is a typical feature besides scratching end excoriations in the cutaneous segment affected. In this series, we present the features of five patients with trigeminal trophic syndrome, highlighting possible confusion with cutaneous lupus. Differential diagnoses, including discoid lupus erythematosus, are discussed, as well as possible treatment modalities.

    Ointment Pseudo-Cheilitis: A Disease Distinct From Factitial Cheilitis. A Series of 13 Patients From Sao Paulo, Brazil
    (2019) NICO, Marcello Menta Simonsen; DWAN, Alexandre Jack; LOURENCO, Silvia Vanessa
    Background: The terms exfoliative cheilitis, factitial cheilitis, and morsicatio labiorum are used to describe self-inflicted lesions of the lip. Objective: Here we report and analyze clinical, pathological, and therapeutic data on 13 patients with a form of factitial cheilitis that we believe should be considered a separate entity. Results: Eight patients were male and 5 patients were female. All patients reported pain and presented with crusts consisting of dried saliva and topical medications adherent to the surface of the lips. These patients expressed great concern with their condition, and reported several previous, ineffective treatments. Simple reassurance only was not effective; saline compresses alleviated symptoms for a few patients. Most patients were lost to follow-up. Biopsies were not performed on all patients. Conclusion: This particular type of cheilitis artefacta has been previously described, but some features described herein are new and allow a specific approach: patient's behavior, the ""protrusion sign,"" and possible improvement with antidepressants. For these cases, we propose the term ointment pseudo-cheilitis because it comprises the nature of the attached material and the lack of true inflammation. Further psychiatric characterization is a logical next step in further characterizing this difficult-to-treat condition.

    Delayed Brain Cyst Formation After Gamma Knife Anterior Capsulotomv
    (2021) KASABKOJIAN, Stephanie Toscano; DWAN, Alexandre Jack; MAZIERO, Maria Paula; SALLES, Antonio de; GORGULHO, Alessandra; MIGUEL, Euripedes Constantino; VATTIMO, Edoardo Fillipo de Queiroz; LOPES, Antonio Carlos
    BACKGROUND: Gamma Knife ventral anterior capsulotomy is an effective option to treat refractory obsessive-compulsive disorder. Although well tolerated, complications can develop years after radiosurgery. We describe a case in which abnormal complications induced by very high doses of radiation evolved. CASE DESCRIPTION: A 55-year-old man with refractory obsessive compulsive disorder was treated with Gamma Knife ventral anterior capsulotomy using a dose of 180 Gy. His obsessive-compulsive symptoms improved, but his condition evolved with a manic episode, cognitive memory changes, visual hallucinations, confabulation, and frontal lobe symptoms. Magnetic resonance imaging showed brain edema in the left hemisphere and a 6-mm brain cyst in the right hemisphere at postoperative month 20. CONCLUSIONS: This case shows the consequences of affecting more fibers related to the anterior frontal region than intended with a radiosurgical procedure and illustrates the importance of careful clinical and imaging follow-up after Gamma Knife ventral anterior capsulotomy.
