Ayurvedic College, Tirupati , Andhra Pradesh , India 3Dept. of Pathology, S. V. Medical College, Tirupati, Andhra Pradesh, India ABSTRACT To assess the efficacy of Leech application in the management of Vicarcik a (Eczema) with Histopathological study, the present study with 10 patients having the classical symptoms of Vicarcika, were randomly selected as per the inclusion and exclusion criteria from O.P.D. & I.P.D. sections of Shalya department, S.V. Ayurvedic Hospital, Tirupati. Minimum 4 sittings of Leech application was carried out with seven days interval. Total duration of treatment was 6 weeks. Biopsy samples were collected from the lesion site before and after treatment. Histopathological examination was done by the pathologist. In eczema (dermatitis) the leech application therapy gives excellent response by reducing the inflammatory component, hyperkeratosis, spongiosis, irregular acanthosis and by evoking a granulation tissue response in the dermis and in most of the cases with complete recovery from the lesion. Most of the cases in the study were chronic dermatitis and sebhoric keratosis, almost all local/focal pigmented lesion is totally relieved by leech therapy especially in cases of sebhoric keratos is. In the present study it was found that, leech application evokes significant changes at histological level specifically in reduction of inflammatory component, hyperkeratosis, spongiosis and irregular acanthosis. It was also found that there was a considerable formation of granulation tissue, which helps in formation of healthy new tissues.

Abstract Sclerotherapy is an effective treatment modality for the management of lower extremity telangiectasias. Although localized dermatologic reactions are known complications of this procedure, systemic reactions are rare. Here, we present a case of a diffuse drug eruption following sclerotherapy for the treatment of bilateral lower extremity telangiectasias. Salient clinical and physical exam findings are described. Management strategies for the treatment of drug eruptions are outlined. This is the first case report that we know of describing a diffuse drug eruption associated with sclerotherapy. It is important to recognize the possibility of diffuse drug eruptions secondary to sclerotherapy treatment so that expectant management may be initiated expeditiously in affected patients.

The terms eczema and dermatitis are often used interchangeably to denote a polymorphic inflammatory reaction pattern involving the epidermis and dermis. Spongiosis refers to intraepidermal edema. Aim: To assess the orientation of collagen in eczematous spongiotic dermatitis. Material and Methods: The present study was done in the Department of Pathology, Sri Manakula Vinayagar Medical College, Pondicherry. Sixty diagnosed cases of spongiotic dermatitis diagnosed over a period of five years were taken in the study. Orientation of collagen was evaluated using Masson’s trichrome stain. Results: Spongiotic dermatitis occurred in all age groups but commonly seen in middle age to elderly. Male to female ratio was 1:1.2 The most common symptom was itching (85%) followed by scaling (63.3%). Most common site was upper extremities (80%). subacute cases were predominantly seen (38.3%) followed by chronic cases (33.3%).

All dermatologists should be aware of these cutaneous lesions, which may be early clinical symptoms of infection. We reviewed the literature on cutaneous manifestations in the PubMed database from December 2019 and June 2020. From the cases described as case reports or series in 57 recent articles, it appears that skin lesions (i) are highly varied, (ii) may not be related to the severity of the condition and (iii) resolve spontaneously in a few days. The frequency of these lesions in COVID-19 patients varies between 1.8% and 20.4%. The major clinical forms described were maculopapular eruptions, acral areas of erythema with vesicles or pustules (pseudochilblain), urticarial lesions, other vesicular eruptions and livedo or necrosis. The lesions were mainly localized in the trunk and extremities. The majority of patients were male, aged between 4.5 and 89 years. A minority of the patients were children presenting with acral, chilblain-like lesions, papulo-vesicular eruptions or Kawasaki disease-like pediatric inflammatory multisystem syndrome.
