Here are the microscopic slide diagrams based on the pathological features described in standard pathology textbooks (aligned with Harsh Mohan's Textbook of Pathology):

1. Tubular (Tubal/Ectopic) Pregnancy - Microscopy

Key Microscopic Features (as per Harsh Mohan / Robbins):

Feature	Description
Chorionic villi	Finger-like projections with loose villous stroma; floating in tubal lumen
Syncytiotrophoblast	Outer multinucleated giant cell layer covering the villi
Cytotrophoblast	Inner single-cell layer (Langhans cells) with pale cytoplasm
Trophoblastic invasion	Trophoblastic cells invade the tubal wall muscularis (unlike normal implantation in uterus)
Ectopic decidua	Decidual change in the tubal mucosa (not always present)
Hemorrhage	Areas of fresh hemorrhage with RBCs - hematosalpinx
Tubal wall	Thinned and distended muscularis; may show rupture
Fibrin deposits	Around the villi and in areas of necrosis

Note: The endometrial biopsy (from the uterus) in such a case shows Arias-Stella reaction - decidual change WITHOUT chorionic villi or trophoblast.

2. Endocervicosis - Microscopy

Key Microscopic Features (as per Harsh Mohan):

Feature	Description
Ectopic endocervical glands	Glands lined by tall columnar mucin-secreting epithelium, located outside the normal endocervix (commonly in urinary bladder wall, parametrium)
Epithelial lining	Single layer of tall columnar cells with pale/clear mucin-rich cytoplasm and basally placed nuclei
Intraluminal mucin	Pale eosinophilic mucin within gland lumina
No endometrial stroma	Key distinguishing feature - NO surrounding endometrial stromal cells (unlike endometriosis)
No hemosiderin	No evidence of cyclic bleeding (unlike endometriosis)
Gland size variation	Glands may be small tubular, irregularly shaped, or cystically dilated
Surrounding stroma	Fibromuscular/fibrous host tissue stroma

Distinction from related conditions:

Endometriosis = endometrial glands + stroma + hemosiderin-laden macrophages
Endocervicosis = endocervical-type glands ONLY, no stroma, no bleeding
Endosalpingiosis = ciliated tubal-type glands (psammoma bodies may be present)

Note: The Harsh Mohan Textbook of Pathology is not available in the digital library; these diagrams and descriptions are based on standard pathological features consistent with Harsh Mohan's descriptions as corroborated by Robbins Pathologic Basis of Disease (available in the library, p. 952 for tubal pregnancy).

Here is the simplified diagram. Key points to remember from this:

What is Endocervicosis? Endocervical-type glands appearing outside the normal cervix - most commonly in the bladder wall or pelvic soft tissues.

The 3 things to spot microscopically:

Tall columnar cells with pale mucin-filled cytoplasm lining the glands
Basal nuclei - nuclei pushed to the bottom of the cells
Mucin inside the gland lumen (pale pink/clear)

The 3 things that are ABSENT (key differentiator from endometriosis):

No endometrial stroma around the glands
No hemosiderin-laden macrophages
No cyclic bleeding evidence

Quick memory trick:

Endocervicosis = Cervical glands only (like the Cervix)
Endometriosis = glands + More (stroma + bleeding)
