[Borderline personality disorder in dermatology]. / Emotional instabile Persönlichkeitsstörung (Borderline-Störung) in der Dermatologie.

Borderline personality disorder is a syndrome of complex psychopathology which is not very common in dermatology. The emotional symptoms are broad and variable, but typically feature emotional instability, intense anger or lack of control of anger, impulsiveness, instabilities in self-perception, problems at work, chronic feelings of emptiness, unstable partnership relations and recurrent suicidal threats. Self-inflicted injuries are common and may lead patients to dermatologists. A 26-year old woman with borderline personality was hospitalized for neurosyphilis. During inpatient treatment she repeatedly cut herself with razor blades. This article highlights the diagnostic criteria and differential approach of the borderline personality disorder in order to facilitate early recognition and therapy.

Systemic eight-cycle anti-CD20 monoclonal antibody (rituximab) therapy in primary cutaneous B-cell lymphomas--an applicational observation.

BACKGROUND: Primary cutaneous B-cell lymphomas (PCBCLs) are characterized by restriction to the skin and a variable but mostly favourable prognosis. Since 1997 the recombinant, chimeric anti-CD20 antibody rituximab has been used in patients suffering from non-Hodgkin's B-cell lymphomas. Different studies have shown that the effectiveness and safety in the treatment of patients with low-grade follicular lymphoma is comparable to or even higher than the standard CHOP chemotherapy. So far it has been unclear whether an extended duration of therapy leads to a benefit for the patients with PCBCL. OBJECTIVES: To evaluate the objective response rate, time to progression, remission quality and histological changes and to compare our data with the literature. PATIENTS/METHODS: Ten patients with PCBCL [eight with follicle centre cell lymphoma (FCCL), one with marginal zone lymphoma (MZL) and one with diffuse large B-cell lymphoma of the leg (DLBCL)] were treated by intravenous application of a chimeric antibody against the CD20 transmembrane antigen (rituximab) with a dosage of eight cycles, 375 mg m(-2) body surface, weekly. RESULTS: The treatment regimen resulted in clinical overall response in 9 of 10 patients, in particular there were seven complete responses (70%) plus two partial responses (20%). The median duration of remission (durable remission, DR) is 23 months (4-30 months) to date. Histological assessment of responses in four patients showed no tumour-specific infiltration. In two patients histology revealed a residual infiltration and in one patient an increasing infiltration. In two patients no histology was taken after treatment; one patient developed a new lesion. No severe side-effects occurred. Observed side-effects were two bacterial infections, two patients with shivering during infusion, one patient with sweating for months and one patient with persisting itching. As expected the B-cell count in peripheral blood was depressed in all patients after infusion. CONCLUSIONS: Intravenous therapy with eight cycles of the anti-CD20 antibody rituximab is a non-toxic and effective treatment for a subset of patients with PCBCL (relapsed, aggressive entity, old patients, multiple lesions) with a long DR.
