Case184:Poroma, apocrine type,(Hidroacanthoma
simplex) |

poroid な細胞からなるintraepidermal flat lesionで、apical
snoutや脂腺への分化像が認められ、apocrine typeのporomaです。 |

Case184:Poroid cell neoplasms |
| |
My diagnosis is Poroid cell neoplsms, Smith-Coburn
type (so-called hidroacanthoma simplex), non-apocrine type.
Because this neoplasm composed of poroid and cuticular cells, but
there is not elongated, dilated tubules and obvious decapitation
secretion. Futhermore, it is not sebaceous differentiation, for
I interpret this is involved normal sebocyte.
For this reason, this is Poroid cell neoplasms, but it does not
fulfills criteria for an apocrine poroma. |

最後の画像のように、poroid cell集ぞく巣とともに、単個でsebocyteが存在する理由は、normal
sebaceous glands では説明できないのではないでしょうか？ |

Re: Case184:Poroid cell neoplasms |

It seems illogical to assume that only cuticular
but not sebaceous cells are the component of this neoplasm. If you
think that the sebocytes are remnant of normal structure in the
basaloid cell nest, you must think that the cuticular cells are
also the normal spiral duct left within it. |

Basaloid cells with ductal and sebaceous differentiation
are proliferating in connection with the epidermis. There is also
peripheral epithelial palisading. Intraepidermal epithelioma with
adnexal differentiation including hidroacanthoma, sebaceoma and clonal
seborrheic keratosis might be the candidates. Considering the minimal
folliculosebaceous differentiation, the first one would be preferable,
probably of apocrine origin. |

腫瘍巣の小さい方も同じだと思いました。 |

case184 question |
| |
The term of "undifferentiated sebocytes" does'nt
make sense. You mean the mantle cells as undifferentiated sebocytes?
Even though the sebocytes are the normal remnant, the normal mantle
cells must also remain within the lesion, and then the lesion must
contain your "undifferentiated sebocytes". |
