Impetigo herpetiformis is a rare dermatosis of pregnancy with typical onset during
the last trimester of pregnancy and rapid resolution in the postpartum period.
Clinically and histologically, it is consistent with pustular psoriasis. This
similarity has led some authors to name the disease "the pustular psoriasis of
pregnancy". We report the case of a patient who developed impetigo herpetiformis in
two sucessive pregnancies.
Proliferating pilomatricoma is proliferative, rare tumor variant of pilomatricoma. It
is a benign neoplasm of hair matrix that can have potentially involve local
recurrence. We report the case of a 60-year-old man who presented an asymptomatic
nodule on the scalp. Histological exam demonstrated a basaloid epithelium at the
periphery, filled with eosinophilic cornified material containing shadow cells. The
tumor was excised and there was no evidence of recurrence one year later.
Hyaluronic acid fillers did not show any fungal or bacterial contamination after being opened and stored at room temperature in nonaseptic conditions. The possibility of reusing the remaining portion of the material in the syringe can be safe and economically viable.
Background: Basal cell carcinoma is the most common type of skin cancer. Although the literature provides a great deal of information on the recurrences of basal cell carcinoma, studies about these indices addressing only the cases in which flaps and/or grafts have been performed for surgical reconstruction of the excision of this tumor are still lacking. oBjectives: To evaluate rates of recurrence of basal cell carcinoma submitted to conventional surgery with pre-established margins and reconstruction by flaps or grafts. Methods: A retrospective and observational study was performed through the analysis of 109 patients, who met inclusion criteria with 116 basal cell carcinomas submitted to conventional surgery and pre-established safety margins, requiring reconstruction through a graft or cutaneous flap. This work was performed the small surgeries sector of Dermatology of the Specialty Outpatient Clinic of the University Hospital of the State University of Londrina, between January 1, 2011 and December 31, 2015. The following data were collected and inserted in an Excel worksheet: name, registration number of the hospital patient, sex, age, tumor location, histopathological type of BCC, procedure performed (type of flap and/or graft), follow-up time, recurrence. results: Of the 116 procedures, there were recurrences in 3 cases (2.6%) that were located in the nasal region and related to sclerodermiform or micronodular histological types. study liMitations: Retrospective nature of the study. conclusion: The present study of the dermatology department of this university hospital showed a low rate of recurrence of basal cell carcinoma in cases where flaps and/or grafts were used in the surgical reconstruction.
Pyoderma gangrenosum is a rare dermatosis of unknown etiology and variable clinical
presentation. The disease is challenging for the medical staff, from the frequent
diagnostic difficulties to the lack of scientific evidence with a good level to
support the management of extensive and refractory cases. Our patient is a 50
year-old man with an extensive and deep ulcer on the left leg, which exemplifies the
therapeutic difficulties inherent to the disease and who, fortunately, has progressed
with excellent result after association of hyperbaric oxygen therapy and skin
grafting to the immunosuppression therapy initially proposed.
Drug-induced acne is a common skin condition whose classic symptoms can be similar to
a rose pearl, as in the case of a male patient presenting with this condition after
excessive use of a cream containing corticosteroids.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
