Is caused by:

Due to________________ such as:

1)

2)

2)

3)

_________ is normal

A

Caused by: masculinization in utero of the female fetus

  3. Androgen secreting tumors of the mother’s adrenal or ovaries

Commonly results from:

Q

Androgen Insensitivity

Caused by:

Karyotype:

Inheritance pattern:

Results in:

Presentation:

__________ is produced by the 46 XY which results in: ______ (_____)

___________ can be seen in partial androgen insensitivity

A

Caused by: genetic deficiency in androgen receptors

Karyotype: XY

Inheritance pattern: 46 XY x-linked recessive

Results in: external female phenotypic development

Presentation: testes are undescended (inguinal canal or labia)

Mullerian inhibiting substance is produced by the 46 XY which results in lack of mullerian duct development (absent uterus or fallopian tubes)

Ambiguous genitalia can be seen in partial androgen insensitivity

well demarcated and eczematoid in appearance with fiery red background with white plaque like lesions

Histologic features: biopsy reveals large pale pathognomonic Paget’s cells

58

recurrence is common
