Summary
Scabies, a common parasitic skin infection, can rarely manifest as annular patches. Diagnosis was confirmed by identifying a scabies mite egg, and treatment with permethrin cream led to full recovery.
Area of Science:
- Dermatology
- Parasitology
- Epidemiology
Background:
- Scabies is a widespread ectoparasitic infection caused by the mite Sarcoptes scabiei.
- It typically presents with pruritic papules and burrows, often affecting specific body areas.
- Atypical presentations of scabies can pose diagnostic challenges.
Observation:
- A case of scabies presenting with well-defined annular patches is described.
- This presentation is infrequent, differing from the typical morphology.
- The lesions were located on the patient's body.
Findings:
- Histopathological examination revealed an ovum of the scabies mite within the epidermis.
- This finding confirmed the diagnosis of scabies.
- The patient's clinical presentation was consistent with scabies.
Implications:
- This case highlights the importance of considering scabies in the differential diagnosis of annular skin lesions.
- Histopathology is crucial for confirming scabies, especially in atypical presentations.
- Effective treatment with topical permethrin cream resulted in complete disease resolution, underscoring its efficacy.

01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.

01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

01:25Endocarditis II: Clinical Features of Infective Endocarditis
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
01:11Papillary Dermis
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...

01:15Reticular Dermis
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

01:29Staphylococcal Skin Infections
Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
