This 57-year-old man presented with asymptomatic, bilateral symmetrical, infiltrative, purplish plaques involved both lower legs of 10-12 months duration. He had no lymph node involvement or distant metastasis. HIV antibody was negative and skin biopsy has confirmed the diagnosis of KS.
A 60-year-old man presented with severe generalized hemorrhagic vesicular rash with fever, arthralgia and headache of 4-5 days duration. The presented photo shows severe involvement of the face by vesicular rash with many vesicles having characteristic central umbilication. Family history of chickenpox was positive in many grandsons of the patient.
A 23-year-old man suffered a more than 3-year-history of palmar psoriasis with exacerbations and partial remissions on potent topical corticosteroids. The well-demarcated,red, scaly plaques involved mainly the thenar and hypothenar eminences of both hands in a symmetrical manner.
Many dermatoses may take linear configuration as a such or as a part of Kobner’s isomorphic phenomenon. Of these dermatoses; psoriasis, lichen planus, plant allergic contact dermatitis, linear epidermal nevi and vitiligo are prototypes. The current case is a 35-year-old man has had linear lichen planus with classical purplish papules extending along the radial side of the index finger of about one year duration.
A 25-year-old male presented with unilateral hyperpigmentation. Most of the right side of the chest was mottled with brownish hyperpigmentation associated with mild hypertrichosis. The defect has been noticed since age of 10 years.
A middle-aged heavy smoker man presented with a blackish hyperpigmented patch on the dorsal surface of the tongue of many years duration. The patient has been advised to quit smoking and to brush the lesion with a teeth brush daily to scrub the hyperpigmented patch.
A 67-year-old woman who is a known case of neurofibromatosis since early childhood presented with myriads of skin-colored soft nodules involving most of the face and many other parts of the body. The face mimicked a “bunch of grape“due to these tumors. The nodules were soft and can be pushed down into the panniculus by light pressure with the finger (“buttonholing”) and spring back when released. Biopsy proved that these tumors are neurofibromas.
An 83-year-old woman with an atrophic bald scalp started to develop many red patches with peripheral black dotty pigmentation of more than one year duration. Later on many ulcers arose within these patches. The biggest ulcer was at the parietal area of the scalp. This ulcer was covered with heaped up friable and hemorrhogic crusty material. Many firm to hard non tender lymph nodes were palpated in the head and neck region. The strange and interesting thing in this case was the lesions clinically start as pigmented BCC and later on they took a SCC-like morphology. Histopathology of many biopsies (early and late lesions) showed basisquamous cell carcinoma.
