Chigger Bites/Mite Bites

• Chiggers, also called harvest mites or red bugs,
  concentrate at sites where clothing meets skin
  hence the eruption of lesions in this child's
  belt area. The mites do not burrow, but larva and
  mouth parts can remain on the skin and may be
  detected in the center of the wheals.

Melanoma

• Acral-lentiginous melanoma is the most common
  type of melanoma in persons with dark skin,
  including Asians, blacks, and Hispanics. It
  primarily affects acral areas, including the
  palms and nail beds, andmost commonlythe soles.
  Nodular melanoma and acral lentiginous melanoma
  usually have a worse prognosis than lentigo
  maligna melanoma and superficial spreading
  melanoma because of the greater depth of invasion
  at the time of diagnosis.
• It usually affects the back in men and the lower
  extremities in women. The lesion initially
  expands radially over several years. The
  irregular red, white, and blue pigmentation
  generally associated with melanomas is most
  evident in this type. Red represents areas of
  inflammation white, areas of regression and
  blue, areas of deep pigmentation and vertical
  growth.

• Can manifest on any part of the body.
• Remember this is a fungus not a worm.

Juvenile Rheumatoid Arthritis

• Complete destruction of the small finger joints
  results in flippersunlike the classic
  swan-neck deformity of adult rheumatoid
  arthritis, where vasculitic lesions also are
  present

9
Lyme Disease

• The characteristic rash of Lyme diseasean
  annular red eruption with a central clear areais
  observed in fewer than 50 of cases. Variations
  include an ecchymosis-like rash, such as the one
  seen here vesicles and diffuse erythema.

Gout Arthritis

Osteoarthritis

• She complained also of stiffness in the region of
  the DIP joints when she arose in the morning and
  after short periods (less than 15 minutes) of
  inactivity. A history such as this, in
  conjunction with the appearance of the patient's
  hand, is typical of Heberden nodes, which are a
  manifestation of osteoarthritis (OA).

Tick Bite Reactions

Heat Rash

• Typically, miliaria rubra arises in hot, humid
  environments the lesions also may appear on
  areas of the body that are occluded by tight
  clothing. Affected sites need to be kept dry and
  cool.

16
Creeping Eruption (Hookworm)

• This disorder is caused by skin penetration of
  hookworm larvae.
• The human epidermal basement membrane does not
  allow further penetration, and the trapped larvae
  randomly creep along the basement membrane.

17
Seabathers Eruption

• After he had been swimming in the ocean, a
  pruritic, erythematous, papular rash developed on
  his trunk, axillae, and groin. Approximately 24
  hours after the onset of the rash, he experienced
  malaise, chills, and a sore throat.
• This boy has seabather's eruption, a pruritic
  dermatitis that occurs after exposure to seawater
  that contains certain species of jellyfish

18
Schistisomiasis Lake Nicaragua

• Both children have cercarial dermatitis, commonly
  known as swimmer's itch. This is a
  hypersensitivity reaction that occurs after
  exposure to schistosome larvae in freshwater
  lakes.

Diabetes/Leg Ulcers

Scabies

• The female Sarcoptes scabiei mite (A) burrows
  into the stratum corneum, where she lays eggs.
  The parasite is transferred by intimate contact
  and fomites, such as infested clothing, towels,
  and bedding.
• Small erythematous papules develop on most
  patients between 4 and 6 weeks after exposure.
  Typically affected sites include finger webs,
  wrists, waistline, nipples, and penis
