The present paper highlights the usefulness of 70% trichloroacetic acid in treating sebaceous hyperplasia in elderly patients. Esthetics are an important issue, and different therapeutic modalities can be used, such as systemic isotretinoin, surgical excision, electrocautery, cryosurgery, topical photodynamic therapy and laser, but all these methods are expansive and invasive procedures that may result in scars, which are more extensive than the original lesions.
Congenital skin aplasia, known more as aplasia cutis congenita (ACC), is a rare congenital disease, characterized by absence of the skin, observed since birth, more often affecting the scalp and rarely the trunk or limbs. We report here for the first time a non-syndromic localized ACC, characterized by a small solitary area of skin atrophy on the cervical area in a healthy 3-day-old female infant.
Hyperkeratotic lesions result from continuous mechanical action on the skin forming a callus or a corn. The accumulation of horny layers will increase pressure, creating a vicious cycle. We present a new approach based on relieving pressure or friction, strictly based on the results of pedography (pedobarography).
Newborns are more likely to develop bruises due to mechanical trauma during birth. Establishing the correct diagnosis in newborns presenting with different skin lesions is not an easy task, and besides the well-known pathology, one must not forget simple posttraumatic injuries. We present three cases that raised questions before establishing that the lesions had been induced by simple mechanical trauma during birth. Trauma-induced skin lesions in newborns may represent an overlooked problem. The three cases presented here are meant to draw attention to the possibility of trauma-induced lesions in newborns, which require only close follow-up and surveillance instead of exhaustive clinical and laboratory investigations, which are inevitably accompanied by anxiety.
Congenital malalignment of the toenail is characterized by the lateral (rarely medial) deviation of nail plates that affects mostly the great toes from one foot or both, but has also been described on other toes, even on the hands. This nail disease is still considered a rare entity, although it is not a rare clinical observation in daily practice. We present a few cases in children and adults, highlighting the diagnosis made by clinical observation, regardless of the different grades of severity of the nail disease. Conclusion: It is of great importance to clinically recognize this entity in young children and to make the correct recommendations.
Background: Daclizumab is a humanized monoclonal antibody against the D-subunit (CD25) of the high-affinity interleukin (IL)–2 receptor, used for the treatment of relapsing-remitting multiple sclerosis with a large spectrum of cutaneous adverse reactions. Case presentation: We present the case of a middle-aged man treated with daclizumab for multiple sclerosis, who developed skin reactions difficult to evaluate. A 4 mm punch-biopsy was taken from the plantar area. Histological examination of the biopsy revealed hyperkeratosis and acanthosis but no parakeratosis, while a discrete inflammatory infiltrate was noticed around vessels in the dermis. Treatment with fluconazole 50 mg/day for 10 days, moisturizers, and grade I topical steroids was followed by slight improvement of the clinical picture. Treatment with daclizumab was not discontinued. Conclusion: The clinical efficacy and side effects of daclizumab have to be reported and confirmed in clinical practice in the following years. Any clinical report can contribute to validate the efficacy and risk of the drug’s administration. Any type of adverse skin reaction must be reported for clarifying the diagnosis.
Introduction: Glomus tumors are rare benign mesenchymal neoplasms accounting for only 2% of all types of soft tissue tumors. Commonly located in the peripheral soft tissues, they are most frequently encountered in the subungual areas of fingers and toes, and very rarely in visceral organs due to the absence of glomus bodies. To date, 22 cases of primary renal glomus tumors have been described in the literature, of which 17 benign, with no evidence of recurrence or metastasis, three cases of malignant glomus tumor, and two cases with uncertain malignant potential. Case report: We report the 18th case of a benign glomus tumor of the kidney in a 49-year-old female patient, presenting the microscopic appearance (round, uniform cells with indistinct borders, scant finely granular eosinophilic cytoplasm, round nuclei lacking prominent nucleoli, arranged in solid sheets, accompanied by slit-like vascular spaces), the immunohistochemical profile (tumor cells showed immunoreactivity for smooth muscle actin, vimentin, as well as for CD34; they were negative for AE1/AE3, desmin, HMB-45, S-100 protein, renin, and chromogranin), and the differential diagnosis of this rare entity (juxtaglomerular tumor, angiomyolipoma, hemangioma, epithelioid leyomioma, solitary fibrous tumor, carcinoid tumor, and paraganglioma). Conclusion: Primary renal glomus tumors are rare tumors that radiologically can mimic other mesenchymal renal neoplasm. Accurate diagnosis is based on the microscopic appearance and especially the characteristic immunophenotype.
Superficial venous malformations can be clinically diagnosed since birth as localized, bluish or purple lesions, especially on the lower extremity, but deep venous malformations are difficult to diagnose only by clinical appearance. The diagnostic algorithm for superficial venous malformations in newborns includes clinical examination and Duplex ultrasonography. The latter allows differentiating tumors (hemangiomas) from vascular malformations and evaluating flow characteristics as well as localizing the site of the malformation.
