Summary
This study details a rare granulomatous variant of pigmented purpuric dermatoses (PPD) in a woman with hyperlipidaemia. The findings contribute to understanding this uncommon skin condition and its associations.
Area of Science:
- Dermatology
- Pathology
Background:
- Pigmented purpuric dermatoses (PPDs) are a group of rare vascular disorders.
- The granulomatous variant of PPD is exceptionally rare, with only 16 cases previously reported.
Observation:
- A case of granulomatous PPD is presented in a 59-year-old woman affecting the arms, legs, chest, and back.
- The patient concurrently had hyperlipidaemia.
- Histopathology showed a lymphohistiocytic infiltrate, granuloma formation, and extravasated erythrocytes.
Findings:
- This case represents the ninth reported instance of granulomatous PPD associated with hyperlipidaemia.
- It is also the fifth case of granulomatous PPD with a lichenoid infiltrate.
- Differential diagnoses including atypical infections, papular sarcoidosis, and generalized granuloma annulare were excluded.
Implications:
- This report expands the literature on the rare granulomatous PPD.
- It highlights the association between granulomatous PPD and hyperlipidaemia.
- Further research may elucidate the pathogenesis and optimal management of this condition.

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

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.

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

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...
