Palmar and plantar hyperpigmentation Macular hyperpigmentation usually involves palms and soles of healthy black people and is characterized by linear hyperpigmented macules. The lesions of Addison's disease, lues, ephelides, nevi and melanoma form the base of differential diagnosis of palmar and plantar hyperpigmentation Pityriasis rosea is characterized by small, fawn-colored lesions distributed along skin cleavage lines Focal linear hyperpigmentation is commonly due to phytophotodermatitis, which is a phototoxic reaction that results from ultraviolet light combined with psoralens (specifically furocoumarins) in plants (eg, limes, parsley, celery—see Chemical photosensitivity) Postinflammatory hyperpigmentation is diagnosed by taking a careful history and examining the skin. Dermal melanosis gives a characteristic hue to the skin colour (grey-purple-brown). Sometimes the diagnosis is only made after skin biopsy. Histopathology reveals patchy epidermal melanosis and/or dermal melanosis The diagnosis can be made clinically based on the presentation of skin lesions with arthritic symptoms and colicky abdominal pain. If clinical findings are inconclusive, a complete blood count,..

INTRODUCTION. A wide variety of lesions occurs on the vulva. Some of the disorders causing these lesions are limited to the vulva, while others also involve skin or mucocutaneous membranes elsewhere on the body. This topic provides a morphology-based classification system that can help clinicians with the differential diagnosis of these lesions. Hypopigmented macules are one of the most common skin lesions encountered in clinical practice. The word hypopigmentation indicates decreased pigmentation, which means significantly reduced melanin compared to the normal skin Skin biopsy shows a thick epidermis with papillomatosis, and hyperkeratosis. Elongated rete ridges, focal cell vacuolization (koilocytotic cells), and parakeratotic cells. PCR HPV-DNA amplification may detect viral antigens including HPV common antigen. In-situ hybridization may identify viral genomic material

The primary differential for melasma includes drug-induced hyperpigmentation or discoloration, postinflammatory hyperpigmentation, pigmented contact dermatitis (Riehl melanosis), acquired bilateral nevus of Ota-like macules (Hori nevus), actinic lichen planus, lichen planus pigmentosus (LPP), erythema dyschromicum perstans (EDP), and exogenous ochronosis Hyperpigmented Lesions on Arms and mixed connective tissue disease are included in the differential diagnosis of generalized morphea. 5 Standard therapy for limited skin lesions.

Differential Diagnosis in Dermatology This website is for medical practitioners seeking a method to diagnose a skin rash. It is not directed at members of the public who should refrain from using it to diagnose their skin rash and instead seek a Doctor's opinion and treatment The differential diagnosis includes a broad list of inflammatory, infectious, genetic, and other disorders, which often can be differentiated based upon clinical features. Diagnostic techniques, such as a potassium hydroxide preparation, Wood's lamp examination, culture, or skin biopsy, may also be useful diagnosis, if lasers or IPLS are indicated, the optimal wavelengths and parameters will be chosen taking into account the skin phototype, origin and depth of the target pigments. Conclusion Although potentially very effective, lasers and IPLS cannot be proposed for all types of hyperpigmented lesions

'blue hyperpigmentation' which may either be due to melanin or due to non-melanin pigments. Differential diagnosis of acquired hyperpigmented macules is endless. The most common dermatological causes of acquired hyperpigmented macules in clinical practice are, (Table 1) 1. Erythema dyschromicum perstans 2 The lesions were asymptomatic and had slowly been expanding over the past eight months. The differential diagnosis for melasma includes exogenous ochronosis, drug-induced hyperpigmentation. The differential diagnosis of round, discoid plaques on the legs includes nummular dermatitis, psoriasis, stasis dermatitis, hypertrophic lichen planus, erythema nodosum, necrobiosis lipoidica diabeticorum, lipodermatosclerosis, and other varieties of panniculitis.

Authors; Authors and affiliations; Dan Lier; Chapter. First Online: 03 May 2013. 2.2k Downloads; Abstract. Lesions which are darker than normal skin can be brown, black, or sometimes blue-gray In fixed drug eruptions, red plaques or blisters form at the same site each time the causative drug is taken; residual postinflammatory hyperpigmentation usually persists, especially in darker skin types. Typical lesions occur on the face (especially the lips), hands, feet, and genitals Hyperpigmented lesions, presenting at birth and during the first few weeks of life, are quite common. Pigmented lesions can range from small and isolated to large and multiple. They can exist independently, or in association with other signs and symptoms, and may lead to the diagnosis of a congenital or genetic skin disease

  4. The lesions are erythematous, scaly patches or plaques with irregular borders which can occur anywhere on the skin. They can become hyperkeratotic, crusted, fissured, or ulcerated and generally occur in sun-exposed areas. On the ear, they are most frequently found on the helical rim or the external side of the auricle
  5. Differential diagnoses. The differential diagnoses for a patient presenting with a subungual lesion are broad. Lesions can be divided into melanocytic and non-melanocytic. They can also be categorised as neoplastic, traumatic, infective, systemic and drug-induced. Figure 2 illustrates the clinical appearance of some common differentials. Figure 2
  6. AN is a skin condition characterised by darkening, thickening and hyperpigmentation of the skin, occurring mainly in the folds of the skin in the axilla, groin and back of the neck. The face and other sites can be affected. Most cases of AN are related to insulin resistance

Skin Lesions and Diagnosis • Skin acts as window in several ways. Two examples: - Point mutations may cause skin and internal change. • Birt-Hogg-Dube Syndrome causes cutaneous fibrofolliculomas, renal tumors, and spontaneous pneumothorax by affecting the folliculin gene. - Hormonal overdose causes skin and internal change Regardless of etiology, lesions invariably appear on the acral skin of the hands and feet following some form of trauma. Characteristic findings on physical examination Lesions are comprised of multiple brown-black or blue-black petechiae, which coalesce to form a central hyperpigmented macule or patch surrounded by scattered satellite lesions. Scaling that results from stretching or scraping of the skin is also suggestive of pityriasis versicolour. Microscopic examination of skin scrapings treated with potassium hydroxide or stained with Swartz Lamkins or chlorazol black can confirm the diagnosis.2 Other differential diagnoses include post-inflammatory hyperpigmentation (or.

Black and brown skin lesions can be considered as melanocytic neoplasms. The essential task is to exclude malignant melanoma. See also the separate Malignant Melanoma of Skin and Skin Biopsy Techniques in General Practice articles.. It is important to bear in mind that younger people in the UK are increasingly being affected by malignant melanoma, with over 900 diagnoses a year Benign skin lesions are non-cancerous skin growths that may be pointed out by the patient or discovered during routine skin examinations. Accurately diagnosing a benign skin lesion and distinguishing it from a malignant condition requires consideration of the physical and histological characteristics of the lesion as well as the patient's.

HYPERPIGMENTED lesions involving the oral mucosa have various pathogenetic causes. The most common lesions are oral and labial melanotic macules. 1,2 The oral melanotic macule presents in patients older than 40 years as a flat, blue, brown, or black, mostly solitary lesion less than 10 mm in diameter. It may also arise on the gingival, buccal, or palatal mucosa. 3 The labial melanotic macule. Tumors are abnormal growths of cells. Tumors affecting the skin or the tissue just under the skin are the most commonly seen tumors in dogs. Skin tumors are diagnosed more frequently than other tumors in animals in part because they are the most easily seen tumors and in part because the skin is constantly exposed to many tumor-causing factors in the environment Search Results: Scrotum, Rash or multiple lesions.
