Nevus lipomatosus cutaneous superficialis (NLCS) is an uncommon benign hamartomatous condition characterized by the presence of mature ectopic adiopocytes in the dermis. It was first reported by Hoffman and Zurhelle in 1921. Clinically they areit is classified into two forms. The classical form is characterized by groups of multiple, non-tender, soft, pedunculated, cerebriform, yellowish or skin-colored papules, nodules, or plaques. The other form of NLCS clinically manifests as a solitary dome-shaped or sessile papule. The classical NLCS is mostly reported to involve the pelvic or gluteal region. We report here a case of adult-onset classical NLCS on perianal area because of its rarity and unusual location. In addition, our patient also had some rare features of NLCS, such as recurrent in nature, presence of foul-smelling discharge, and comedo-like plugs on the lesions.
Pemphigus vegetans is a rare variant of pemphigus vulgaris that is characterized by vegetating lesions primarily in the flexures. We report a 45-year-old male patient with an unusual presentation of the disease. A careful analysis of the clinical and laboratory findings enabled us to reach a diagnosis and successfully treat the patient.
Blastomycosis is a chronic granulomatous and suppurative mycosis, caused by Blastomyces dermatitidis, which in the great majority of cases presents as a primary pulmonary disease. Primary cutaneous blastomycosis is very rare. We present a 57-year-old female patient with a solitary, slowly progressive nodule over upper lip of 2½ months duration. Initially, differential diagnosis of cutaneous leishmaniasis, pyoderma and deep mycoses were entertained. Slit smear preparation was suspicious of deep mycotic infection which was subsequently confirmed by biopsy and culture.
Testing life cycle poses a problem of achieving a high level of software reliability while achieving an optimal release time for the software. To enhance the reliability of the software, retain the market potential for the software and reduce the testing cost, the enterprise needs to know when to release the software and when to stop testing. To achieve this, enterprises usually release their product earlier in market and then release patches subsequently. Software patching is a process through which enterprises debug, update, or enhance their software. Software patching when used as a debugging process ensures an optimal release for the product, increasing the reliability of the software while reducing the economic overhead of testing. Today, due to the diverse and distributed nature of software, its journey in the market is dynamic, making patching an inherent aspect of testing. A patch is a piece of software designed to update a computer program or its supporting data to fix or improve it. Researchers have worked in the field to minimize the testing cost, but so far, reliability has not been considered in the models for optimal time scheduling using patching. In this paper, we discuss reliability, which is a major attribute of the quality of software. Thus, to address the issues of testing cost, release time of software, and a desirable reliability level, we propose a reliability growth model implementing software patching to make the software system reliable and cost effective. The numeric illustration has been implemented using real-life software failure data set.
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.
