Summary
Ovarian lipoleiomyoma, an extremely rare tumor, presents a diagnostic challenge. This case report details a 57-year-old woman
Area of Science:
- Gynecologic Oncology
- Pathology
- Radiology
Background:
- Ovarian lipoleiomyoma is an exceptionally rare benign neoplasm.
- Diagnosis can be challenging for healthcare professionals.
- Literature predominantly features elderly patients.
Observation:
- A 57-year-old postmenopausal woman presented with abdominal pain.
- Radiology revealed a heterogeneous left adnexal mass, mimicking a dermoid cyst.
- Microscopic examination identified adipocytes and smooth muscle fascicles.
Findings:
- Histopathology confirmed the diagnosis of ovarian lipoleiomyoma.
- This neoplasm consists of mature adipose tissue and smooth muscle.
- The case highlights typical and atypical features.
Implications:
- Increased awareness of ovarian lipoleiomyoma is crucial for accurate diagnosis.
- Radiologists and pathologists should consider this rare entity in differential diagnoses.
- Further case reports are needed to understand its clinical behavior.

01:27Ovarian Cycle
4.1K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

01:30Hormonal Control of the Ovarian Cycle
6.9K
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

02:55The Nucleolus
10.4K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

01:21Frequency-dependent Selection
24.2K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

02:05Gene Evolution - Fast or Slow?
8.2K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

01:05Long-term Depression
33.3K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.
