6. Measles Measles pneumonia. Histology showing mononuclear cells infiltration and multinucleate giant cells

8. measles The minute white dots seen on the inflamed buccal mucosa are koplik’s spots

9. Measles Measles, with koplik’s spot on the buccal mucosa. This is an unsually severe case, enough to cause considerable discomfort when feeding.

11. Measles The rash often begins behind the ears. Koplik’s spots were visible on the buccal mucosa.

12. Measles The rash is already prominent on the face and is spreading down the body onto the trunk and extremities

14. Measles During the healing phase, a transient brown staining of the skin maybe apparent in white children.

18. Rubella Although the rash is quite profuse, the elements are discrete except on the face, which shows general flushing.

19. Rubella A typical diffuse macular rash over the trunk.

20. Rubella Close up of the rash on the trunk.

23. Roseola infantum Human herpes virus type 6. Electro micrograph of extracellular, mature, enveloped HHV-6 virus budding from a cell.

24. Roseola infantum Electro micrograph of HHV-6 capsids in a cell nucleus.

26. Roseola Infantum Non specific maculopapular rash with a central distribution developed as fever, subsiding on the third of illness.

30. Erythema Infectiosum The rash on face is frequently described as having a “slapped checks appearance.”

31. Erythema Infectiosum The rash on the extremities often clears centrally to produce a lace-like appearnce.

34. Herpes simplex Electron micrograph of HSV from vesicle fluid.

38. Herpes Simplex Primary infection on the wrist of a young man.

39. Herpes Simplex Genital infection in an infant due to implantation of the virus carried on the hand from primary herpetic stomatitis.

41. Herpes simplex Recurrent infection in a zoster like distribution over the face.

43. Herpes simplex Severe lesions with skin necrosis in a patient with leukemia.

45. Herpes simplex T zanck test preparation showing multinucleate giant cell.

49. Varicella Chicken Pox Electron micrograph of enveloped virus particles from vesicle fluid.

51. varicella Within a few days of early rash, most of the lesion have become scabs of varying size.

53. varicella General view of severe rash showing characteristic distribution of lesions, with lesions most numerous centrally.

54. varicella Shallow ulcers on the hard palate.

55. varicella Lesions commonly occur within the mouth.

57. varicella In this young boy the lesion are most confluent in the antecubital fossa and over the neck areas where he had previously suffered from atopic eczema

59. varicella Scratching of the lesions not in frequently leads to secondary infection with streptococci or staphylococci and hence cellulitis around individual lesions.

60. varicella Purpura fulminans and disseminated intravascular coagulation complicating chicken fox in immunocompetent adult woman.

65. Shingles When it occurs in a child as young as this 8 month old it is often as a result of primary infection in utero.

66. Shingles High power view of base of vesicle showing inclusion bodies.

68. Shingles A bond of faint erythema in the distribution of an intercoastal nerve, the first physical sign of shingles, can be seen. The patient had been in pain for several days.

69. Shingles A typical mature rash showing regular vesicles of varying size with an erythematous base.

71. shingles Rash involving maxillary division of the trigeminal nerve.

72. shingles The most frequently affected dermatome is that of the opthalmic division of the trigeminal nerve.

73. shingles Lesions in the distribution of the maxillary division of the trigeminal nerve.

74. shingles Lesion in the distribution of the mandibular division of the trigeminal nerve.

77. Molluscum Contagiosum Electron micrograph of the virus, appears as a cylindrical shape with rounded ends and a criss-cross pattern of nucleoprotein strands.

78. Molluscum Contagiosum Several fleshy lesions with ambilicated centers on the face. They tend to regress and disappears after some months.

80. Molluscum contagiosum Orf. Papular lesions on the hand. Patient also has severe erythema multiforme with arthritis. The proximal interphalangeal joints can be seen to be swollen.

81. Molluscum contagiosum Orf. Large pustular lesion on the hand of a farm worker.

82. Molluscum Contagiosum Orf. Early lesion on the face.

86. Warts Electron micrograph showing papiloma virus.

89. warts Common warts. Hand and fingers are common site.
